Here’s a scenario you may not like, but could happen every day, because it’s always viruses season for computers. You’re working on an important project and suddenly start noticing annoying pop-ups displayed on your computer. Also, it takes too long for your files or computer apps to load. You wait and wait until you start asking yourself:

 “Does my computer have a virus?”

Unfortunately, the answer might be “yes” and your computer could be already compromised with viruses or advanced malware that are slowing down its activity and performance.

This is one of the signs that show your PC might suffer from a malware infection. There are more of them you need to be aware of and understand, so you can quickly take action.

In this article, we’ll show you the most frequent warning signs of malware infection and what can you do about it.

Quick links with what you’ll find out:

1. Your computer is slowing down
2. Annoying adds are displayed
3. Crashes
4. Pop-up messages
5. The Internet traffic suspiciously increases
6. Your browser homepage changed without your input
7. Unusual messages show unexpectedly.
8. Your security solution is disabled
9. Your friends say they receive strange messages from you
10. Unfamiliar icons are displayed on your desktop
11. Unusual error messages
12. You can’t access the Control Panel
13. Everything seems to work perfectly on your PC

Scenario 1: “My computer applications run slow lately and it takes longer than usual to start”

If you’re dealing with this scenario, it could indicate the presence of viruses on your computer. We know, it’s so frustrating to see it loading slowly. It is a known fact that one of the malware’s main activity is to slow down your operating system, whenever you’re navigating on the Internet or simply accessing your local applications.

What can you do? First off, you need to check for causes and find the real problem.

Here are some of the most common causes that slow down your PC:

  • Your system’s RAM memory is low and might be caused by the number of high apps you’re currently using. Windows Task Manager is a great tool to look for programs which use the most of your RAM memory. Press CTRL+ALT+DELETE simultaneously on your PC, choose Task Manager and will open a list of your current apps you have open;
  • There is no storage space on your hard disk, so you need to check your files and documents stored there and do a cleaning;
  • This behavior is particularly happening when you’re browsing the Internet, so you need to check your browser’s Settings, then clear your browsing data;
  • A fragmented system which means that the storage space is used inefficiently and reduces your PC’s performance;
  • Your Windows OS hasn’t been updated or you’re using outdated drivers.

If you have already thoroughly verified these possible causes and all seems to work just fine, you can start considering a potential malware infection. Use these tips to help you optimize and speed up your Windows operating system.  This article shows 5 ways to keep an eye on those programs accessing your drives.

Scenario 2: “I keep getting annoying ads that are opening randomly or strange messages on my computer’s screen”

Unexpected pop-ups which appear on your screen are a typical sign of a malware infection that wreak havoc on your computer. This form of malware is known as spyware and is designed to collect and steal users’ sensitive data without their knowledge.

In this particular case, the main issue is created not only by the numerous pop-up windows that affect your Internet browsing but also because it is quite difficult to remove them from the system.

These pop-ups are not only frustrating, but they usually come bundled with other concealed malware threats and could be far more destructive for our systems. They could be disguised as legitimate programs and actually track your web browsing data or monitor your online activity to collect passwords and other personal information.

We strongly recommend to NEVER CLICK on a suspicious pop-up!


Try one of these free spyware removal tools to get rid of those annoying pop-ups or strange messages.

Also, to better keep your computer away from malicious threats, make sure you use these security measures:

  1. Do not click on pop-up windows
  2. Don’t answer unsolicited emails or messages
  3. Be very careful when you are trying to download free applications from various websites

Use this guide that includes useful steps that will make the removal process easier and more effective, as well as your Internet navigation hassle-free.

Scenario 3: “My laptop keeps crashing when I watch Youtube videos or play games. It simply freezes, then a blue screen shows up”

Oh, I know this one. It happened to me with my current laptop so many times, and was quite frustrating. It crashed so many times and got that popular BSOD (Blue Screen of Death). Then it restarted and told me that Windows was recovering from an unexpected shutdown.

You are probably familiar with this kind of error, don’t you?

There might be two things causing this type of issue:

  1. You could be dealing with a technical issue caused by a potential incompatibility between your software and/or hardware
  2. Or it may be a malware issue.
  • If you suspect the technical problem, it may lead to this:

Various programs are running on your PC which may be in conflict? Are there any orphaned registry keys which have not been removed that could eventually crash your system?

Orphaned registry keys are pieces of data information that have been left behind during the process of uninstalling several programs from your computer. They don’t only take up unnecessary space on the PC but can cause a serious issue for its proper functionality.

How to fix this: Use the Registry Editor (Regedit.exe) that can be opened in the search bar of Windows where you select the run command. The daunting part of this process is that you have to manually remove these orphaned keys.

Our recommendation is to run an automated cleaning session using a specialized program like CC Cleaner which is free (Two versions of this tool were recently compromised by malicious actors who spread malware inside it, but CCleaner is safe now) and will  automatically scan missed and unused keys while doing a backup of your data before the actual cleaning.

First of all, install the CCleaner program, click the Registry icon (as displayed in the image below), select the items you want to delete, then Scan for issues and a list of potential issues will be generated. After the scanning is done, you can review the list and click on Fix selected issues to solve the outstanding Registry issues. You will be asked to backup changes.

  • For malware infection: run a complete scan on the system with a good antivirus product. If you have a dilemma about which antivirus is the best one, we wrote this useful guide on how you can find the right one for your needs. It is also important to rely on another layer of security on top of antivirus to better fight against online threats and proactively block them.

If your programs or your system crash constantly or the infamous BSOD (Blue Screen of Death) appears regularly, it’s a clear warning that your system is not working properly and you should look into it.

There are two things that can cause this type of issues:

  1. You could be dealing with a technical issue caused by a potential incompatibility between your software and/or hardware
  2. Or it may be a malware issue.

If you suspect a technical issue, multiple software problems may lead to this.

Scenario 4: “ I started getting this popup message <you’re running out of disk space on Windows (C:)”

If you are receiving this warning message, it means that there’s no free space left on a particular partition (in this case, C) on the main hard drive in your computer. More and more users are reporting this issue.

The cause? Here’s what Microsoft has to say about this:

This behavior can occur if the free disk space on your computer has dropped below the low disk space notification threshold associated with the Disk Cleanup utility.

low disk space 1

How do I fix this? First of all, you need check if your physical storage space has been increasing lately or if some of your files disappeared or changed their names. Also, make sure, you delete all those old or unnecessary files that can lower your PC’s performance.

This could be another sign of malware infection, since there are so many types of malicious programs which use different methods to fill up all the available space in the hard drive and cause it to crash.

Scenario 5: “For quite some time, every time I start my PC, I notice that the Internet traffic suspiciously increases”

If you saw this message, chances are there is an unusually high network activity happening on your PC that could lead to a malware infection.

There are cases when the user is not connected to the Internet through his browser, and there is no program that may connect to online servers to download or upload any data, but high network activity can still be observed.

What can I do? Have you checked for:

  • The last Windows update for your computer?
  •  Is there any program or application that’s downloading any data?
  •  Is there any update for a certain app running at this moment?
  •  Is there a large download that you started and forgot about, which may still be running in the background?

If the answer to all these questions is NO, then you should check where all that traffic is going. Here’s how to do this:

  • Check for a malware infection, by using a good antivirus product to fully scan your system.
  • If you suspect your computer has been infected by a dangerous financial malware, we recommend using a specialized security suite designed to address advanced and new online threats.

Scenario 6: “My homepage has changed and I don’t remember doing it myself”

If you noticed this unusual behavior or a new toolbar showing out of nowhere, or you’ve been redirected to a different web address than the one you’ve initially accessed, they could be signs of a malware infection.

It usually happens when you visit a website and you accidentally click on a link or a pop-up window. This triggers the unwanted software to download and install on your device. Its effects are not only annoying, but also malicious.

What to do? Run a complete scan with your security software as soon as possible. Why? Because these type of threats don’t go away easily.

Scenario 7: “My PC is acting weird because I get unusual messages that appear unexpectedly.”

I get this! That’s usually the type of warning message that could make you wonder “What’s going on with my computer?”

Here are some frequent warning signs to watch out!

  • Suddenly you see programs opening and closing automatically
  • Your Windows OS is shutting down unexpectedly, without any reason
  • You’ve noticed strange windows when your PC tries to boot
  • Windows tells you that you’ve lost access to some of your drives.

Although the root cause may be a technical issue, it could also be a warning sign that malware has taken over your computer and is slowing down its activity.

Has your computer suffered a malware infection lately?

How to mitigate the impact of a malware infection?

Follow these steps:

1. Keep your Windows system up to date

2. Scan your computer with an antivirus product

3. Install a proactive security solution to enhance your computer’s protection

4. Consider reinstalling your operating system. This 13-step guide will show you how to secure your PC after a fresh (re)installation.

Scenario 8: “I use an antivirus product and keep getting the message that <Protection is disabled>”

If you observed that your antivirus solution doesn’t seem to work anymore or the Update module is disabled, then you should check immediately for ways to fix it.

Did you know that some types of malware are sneaky and can disable your security solution?

 Well, yes, they are designed to leave users without any defense and making difficult for users to detect them. If you already tried to reboot your computer, closed and opened the security solution and all your troubleshooting efforts were useless, you could consider the malware infection scenario.


This is especially the case, because it’s a known fact that traditional antivirus solutions can’t easily detect, block or remove new and advanced malware( such as ransomware, adware or financial malware). Thus, you can get exposed to all kind of attacks, and we strongly recommend enhancing your protection by adding multiple layers of protection.

Read these 10 reasons why second-generation  malware evades antivirus detection.

Scenario 9: “My friends tell me they’re getting strange random messages from me on Facebook, which I didn’t send”

If your friends recently got several strange messages/emails or suspicious links from you, and you didn’t send, it’s likely that you’ve been infected with malware. Here’s a recent example of malware spreading via Facebook Messenger and tricking users into clicking on links they’ve received from one of their friends.

But first, check your online accounts and see if those random messages were actually sent from one of your accounts. If something like this happened, take immediate action by following these security measures:

  • Log out of all your accounts. For most of our online accounts, we log in to multiple devices and we often forget to log out. So make sure to log out from your online accounts on all connected devices.
  • Use unique and strong passwords for all your online accounts. Always remember to change passwords for your online accounts! NEVER set the same passwords for multiple accounts, because if you are hacked, all your accounts will be exposed and lose important data stolen. This password security guide will help you master passwords like an expert.
  • Start using two-factor authentication RIGHT NOW. Do you want to increase your control over your accounts’ security? Then add this second security layer that will ask for an extra step in the login process, along with your credentials.

Scenario 10: “There are these new, yet unfamiliar icons on my desktop that I don’t recognize”

If you’ve been noticing unknown and new icons on your PC, you most likely downloaded by accident these sneaky programs called PUPs (Potentially Unwanted Programs). They are malicious programs that can do a lot of damage and expose you to data leakage, displaying annoying ads or pop-ups on the screen, or adding toolbars on your browser.

If you’re infected with PUPs, have a look at this guide showing how to avoid these unwanted programs and remove them from your computer.

Scenario 11: “Sometimes I see unusual error messages displayed on my computer”

An error message like this one could indicate that there’s a bug in your system that needs to be fixed, or it could be a warning sign of malware infection. These types of error messages showing missing or corrupt files folders suggest that your PC has been compromised and its performance is affected, which makes it run slowly.

How to fix this: Do a full scan of your PC and see if any viruses are detected. Also, make sure you have the latest updates installed on your operating system and regularly check for security patches, applications updates, and drivers.

Scenario 12: “It seems that I can’t access my Control Panel by clicking on the button”

If you are facing this issue and your Control Panel will not open, it means that your computer is having a technical problem and is not functioning correctly.

How to fix this: The first thing to do is run a full scan with your antivirus software. Then, see if you can open Control Panel in Safe Mode and follow these steps described here. It could also be another sign that your computer is vulnerable and exposed to potential cyber attacks. After running a full scan with your antivirus product, use also a proactive security solution to keep your confidential information properly safe.

Scenario 13: “Everything seems to work perfectly on my PC. Are any chances to be paranoid and still check for malware?”

When it comes to data protection, it is essential to be a little bit paranoid and very careful, even if everything seems to look normal. Why? Because cybercriminals are ingenious and can hide malware in the most unexpected places, leaving no visible marks and still infecting your computer.

Everything may seem to work perfectly normal on your PC until a bot on your system could silently wait for instructions to access and collect your most sensitive data.

Can you avoid malware infections?

Yes, you definitely can, if you’re paying close attention to these early malware infection signs and prevent them from happening. Make sure your operating system, browsers, and plugins are always up to date, because keeping your software patched can keep online criminals at bay.

I run my laptop without battery, but its too slow now,i cant work on it. any solution for this?

I was in doubt if there is any virus in my windows desktop, but later i realized after these steps i had no antivirus. Thank you for the guide.

My laptops keyboard is misbehaving sometimes.Sometimes mouse pointer is not working or sometimes some keys are not working. I have an antivirus software but i haven’t update its database. Its license is not expired. what should i do?

If you think, It is causing issue due to antivirus then i would like to suggest you that as it is expired now so remove it completely from the system and reboot the machine once.

I suspect a person I know affected my mac with malware, it is slow and I have incessant pop ups. I have a pending criminal petition against this person but need evidence that he has hacked my computer, is it possible to find evidence of that on my mac? Thank you.

What to do with all those cyber muggers? My email got blocked by one of such (My Faster PC) and they asked me for $200 to fix the problem. Is anything the FBI can do to fix those con jerks?

Contact Federal Trade Commission at 1-877-FTC-HELP. I too, was a recent victim.

How we can find the virus such as ransomware or financial malware in our computer, what are signs we must aware of?

do we need some other kind of antivirus to rip off from these viruses? if yes how much Heimdal gives security for these?

Good Article
keep it up
good to share for society,

Hey Andra, Yday when i was browsing some genuine site, my laptop gives pop-up that malware detected. I updated default anti-virus system, what should i look more for? Hope my system is secure. Thank in advance.

Hi John! I’d recommend you use this guide to look into the issue more thoroughly:

hi i have a qustion my pc is keeps ruuning a scan disk then when i type in a explorer window i type in a web broswer and it reboots
also when i type something it goes to the next window without me pressing next
any help would be helpful

You can try this guide and see if you find anything malicious on your PC:

my home computer is really slow but we have really good internet.

Hi, I have a problem that I just cant find the solution to. My laptop is always connected to the WI-Fi. I have an antivirus program enabled. What happens is that even when I am not on the browser (like preparing a report in excel), even then my antivirus shows messages like “We have blocked this website for your safety”. And the trend is that most of those sites blocked are wordpress blogs that are probably spam. Just today, those sites turned into pornographic sites(and I might add ashamedly that the sites it tried accessing corresponding to my interests in that dirty field). It seems like my system is trying to access these sites in the background while also getting information and usage patterns on me and the antivirus is constantly blocking it. I have run two full scans, one in safe mode, one normally. Both times the scan showed no threats. Pls advise me what to do.

It seems like you could greatly benefit from what Heimdal PRO can do in terms of traffic filtering (which is more than the web traffic filtering in most AV products). But if you’d rather try another option, I’d recommend you try this guide and see if you find anything malicious on your PC:

my computer is freezing like when you log on the mouse is stock and the websites wont open

Hi Chantel,

Sorry to hear that, but we don’t provide malware removal support. You can use this guide to start cleaning up your PC:


what if having immediately off while using your loptop? what the problem of this?

Found this while searching for a solution… but my issue is not on here. For the past week or so, every time we get on a search engine (we have google chrome, firefox and microsoft edge) (on a three-month old PC) it works at first, and then stops working…ALL of them! I ran free versions of malwarebytes…nothing, and superantispyware …cookies. I looked at programs in the control panel…nothing unusual popped up. When I restart the computer, I am able to get on the search engines. Using another device, I looked up possible solution, and for google chrome, it said to clear browsing history. I did, and that seems to have helped (I am on this site now!). I will try the same with the other search engines. But it seems that there should be something I need to clear off the computer. Any ideas?

Hello there! What I would do is also run a cleaning session with CCleaner. Maybe that can help.

You should try Google Cleanup Tool if you are still experiencing issues. URL:
Also, check on the extensions in each browser as you may potentially have adware such as unwanted toolbars. The Google Cleanup tool will scan your browser for known programs and will reset your browser “This will reset your startup page, new tab page, search engine, and pinned tabs. It will also disable all extensions and clear temporary data like cookies. Your bookmarks, history and saved passwords will not be cleared.”

You can also give Norton power Eraser a try, here is the URL:
When you use Norton Power Eraser, scan for unwanted applications then scan for risks. Save all of your files as you will be required to restart your computer for a rootkit scan. Do not go into the advanced settings unless you are considered an advanced user or a technician.

Hopefully, I helped in some way.

Great advice. I am going to share it with my students.

This is a good list. Some of these problems took me back a while. That IE toolbar picture is crazy haha. I think one of the most common one’s I see is the browser homepage being changed.

Another thing that catches a lot of people is the “Malware” that they install when installing another program. Spamming the next button can get you into trouble if one of those next buttons has a checked box that makes you agree to install something else. These have got me a couple times before as well.

I think we all fell for these at some point, just like you said, Dave. I’m glad you enjoyed the article and thanks for taking the time to share your thoughts!

Hi,my phone crashes on an app does that mean I have a virus also it says I have a virus and tells me to click on it do i

My phone has same issue, and other than that, my PC too gets hang up after 5 min usage. don’t know if both device are having virus attack.

Hi Andra. I have a quick question. If a pop-up appears on screen that says you are currently being hacked, should I trust those pop-ups if they aren’t from my anti-virus software? Thanks!

hi, in all my browsers( Mozilla, Google Chrome, Internet explorer) when i try to open “” or “ ” it gives me an error stating that ” your connection is not secure” pleases pleases help me to fix this, idont know what to do.

Hi there! Unfortunately, we can’t help with specific issues. Please verify your software and hardware for issues.

Are you currently a student using an account created by the school or your network administrator? (You may be the administrator) If so, log out of that account or start browsing in guest mode. That way, you can browse whatever you want. The same thing happened to a friend of mine. Oh, and another fix, do you currently see, or have. SafeMode enabled anywhere? If so, disable it. If there is no option to disable it, contact your network administrator or provider. Hope this helped!

I have a problem with my PC. I tried to download something and now something called arcing pops up and says it has stopped working. What should I do. I have a HP windows 10 laptop

Hi Alexander! We don’t provide assistance for malware infections for individual users, but you can certainly find help here: It seems that you’re infected with adware:

I’m using McAfee and Heimdal on my HP Laptop. My internet connection is 3G & have some speed problem. So patches are not updated many times. Should I need some more security software? Please suggest.

Hi there! I think that your internet provider may be the cause here. However, you can always send us an email at if you think we can help.

The disk continues to exhibit excessive activity even when you don’t use it…
I scanned with Malwarebytes Anti-Malware (updated) but the Heuristic Search
didint seek anything… anysuggestion?

Many things could cause this behavior, Roy, not only malware. It really depends on the hardware and software you use. Maybe someone from these forums can help:

Can a malware still don’t show these signs and lurk in the system?

Can you please help to suggest any best antivirus for my dell laptop ?

We actually have a guide dedicated to just that:

Thank You Andra Zaharia For Refer this url To Mr. Ranjeet Singh, I also went through it and found that… mcafee antivirus is the best no doubt its quality and another one i was suggested by Laptop Repair Home Service . I m having nice experience by using Quick Total Security as well.

Can someone please help? I was on my laptop looking at a website and all of a sudden this thing popped up and it said: Your laptop has been hacked and blah blah blah and I don’t remeber the rest and I don’t know if it’s real or not. Please help.

So sorry to hear about your issues, Leen. I can’t tell by the details, but I’m sure you can find help on any of these great forums:

Most of those are scams designed to make you call a number in India to some boilerroom where they try and get you to give them access to your computer online, where they steal all of your personal information. I get these all the time—don’t ever call the phone number that they give you—it’s a scam.

how about Bug they keep showing up when i press a app

I can’t open some website, it said “What can I do to prevent this in the future?

If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware. If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices.”

my computer suddenly gets distorted example the time in the right appears on the left behind the widows start menu and when my mouse rolls over icons they change pictures to other icons what is that whats wrong with my computer is it really because i didn’t upgrade to win10 and then reformatted my computer after all support for win7 stopped?? OMG I’m going nuts I reformatted my computer 5 times now.

Sorry, Teeri, but this looks like a problem you’ll have to contact Microsoft about (at first). Maybe you can use one of these forums to find help:

hii.. i am using windows 8 ,sometimes it works so slow to loading the web page on internet and it also show with “Mozilla Firefox not responding”….what i do..please give any opinion on it,,your cute boy_ vicky

Thank you for this information about knowing if a computer is infected or not. It is good to know that slow downs are a warning sign to pay attention to. This would be a problem because it could end up influencing the hard drive. Something to consider would be to seek professional help as soon as a problem is suspected.

Thrilled we could help, Jade! I hope you never have to deal with such an issue.

i got better solution to this all problem run them first in the virtual machine and leave it, in couple of minutes if strange happening to VM. or an annnoying pop-up to your screen, or system fails thats it its a malware.

Interesting. I have tried some scanning tools but most of them give you more malware. Do you know of any safe scanning software?

I will double check this symptoms in my PC. Ive experienced irregularities lately. Aside from ESET Antivirus, what other AV softwares can you suggest?

These are really helpful tips. Thanks for sharing. Most of these things were happened to me before. Then a friend recommends me to use ESET Antivirus and since then, none of these things are happening to my system anymore.

I was already familiar with all warning sings on the list, except #6 UNUSUALLY HIGH NETWORK ACTIVITY. I will be trying Glasswire now.

I have a very unusual problem. There is one and only one website that I sometimes access where my letter U does not work at all. I try to leave a message or make comments and everywhere a letter U should be, there is nothing, not even a space. It’s like I just misspelled a word. Therefore, any message or comment I try to leave does not make sense. I have absolutely no other problems with my computer. Do you have any suggestions? Also, I use Google Chrome for Internet access. Thank you.

Hi Patricia,

This sounds very strange indeed. I couldn’t tell if it’s a hardware or a software problem, so I recommend you ask someone to take a look at it, because we don’t offer tech support and it’s difficult to offer specific advice from afar.

Best of luck!

I have had the very same issue mentioned above.. although it seems to have now gone away.. it was with Facebook messenger.. most frustrating as you can’t even type a Capital U to around the issue.

I believe it’s was Facebook but have been Viber ?

I have a problem before with malware. Usually when your computer is infected by it you will notice that your computer starts to slow. One way to address the problem is update your antivirus software and run a scan to rule out the problem. If you have time please check out Computer Repairs Adelaide

How funny to run into a Romanian. I am a Romanian myself and I was researching an issue that I have with comments. Since a few days ago when I try to submit a comment on a blog, the computer is warning me that I am sending it on a form that is not secure. I have no idea what that means. Should I not send it? Does my computer have malware?

Hi Anda! So nice to have you here!
That sounds strange indeed. Our blog uses HTTPS, so the data you send us is encrypted for safety. Have you experienced this with other blogs as well?

Hi Anda,

Sorry that I only saw your comment now.

Our website is protected with SSL. Do you still have this issue? If so, we’ll look into it to make sure everything is in order.

Both Disqus and the Heimdal blog are safe to use, so maybe it was a temporary issue.

Thank you for your feedback!

and also check your internet connection, some problem laid to the internet provider

funny how I ran into a Romanian author 😀

Updating operating system may improve the reliability speed and security of our computer. It is essential to improve and update your operating system from time to time. Latest version of OS allows you to do the updating automatically although may take a bit of time but it worth the effort.
