This type of malicious software can infect your computer without a single click
- see the content of the website you’re on
- perform various actions (example: fill out a form or download a file from a website)
- see the online ads (banners) on that website, etc.
Because online browsing is one of the strongest online habits that users have, cyber criminals target exactly that. Online attackers frequently redirect users to compromised websites. These can be either created by them or they can be legitimate websites they’ve hacked into. According to Sophos, “82% of malicious sites are hacked legitimate sites”! Source: Naked Security blog by Sophos What defines an infected website is that:
- cyber attackers have loaded malicious content or malicious software from a remote server.
- You, as a user, unwittingly browse the compromised website.
- They are executed through your browser, triggering the malware infection.
- The exploit kit used in the attack (hosted on the exploit server) probes your system for software vulnerabilities.
- Once the exploit finds the vulnerability, it uses it to gain access to your PC’s functions.
- This grants the exploit kit the right to execute code and download additional files from the Internet with administrator privileges.
- In the next step, malware will be downloaded onto the PC and executed.
- The malware can perform damaging functions on the PC. It can also collect information from the infected system and send it to the servers controlled by cyber criminals.

Unfortunately, once a .JS file has been saved to your hard disk, Windows will run it by default outside your browser, using a system component called WSH, short for Windows Script Host. A standard system program called WScript.exe (or its companion, CScript.exe, for command-line scripts with no graphical interface) will load your script, feed it into WSH, and then run it with all the power that a regular executable program would enjoy.

7. Browser add-ons and plugins – these can be either infected or they can load external content loaded with malware from external sources.
Source: IT Portal Six months later, a new ransomware strain called RAA appeared. It featured a dumfounding feature:
- Keep your software updated at all times (your browsers, apps, operating system, etc.)
- Use a strong antivirus product with extensive capabilities
- Install a traffic filtering solution that can ensure proactive security
- Never click on links in unsolicited emails (spam)
- Never download and opening attachments in spam emails
- Keep away from suspicious websites.
And if you want to go the extra mile, here’s a setting you can adjust in your Chrome browser:
- Click the Chrome menu Chrome menu in the top right hand corner of your browser
- Select Settings
- Click Show advanced settings
- Under the “Privacy” section, click the Content settings button.
If malware attacks such as the ones I mentioned ever made you feel helpless, there’s no reason to feel this way. The entire process may be complicated for cyber criminals, but there are plenty of protection methods available. You should be unwilling to succumb to fear and adopt the “there’s nothing I can do about it” attitude. Educate yourself, build a multi-layered security system and you’ll be safer than most Internet users will ever be. You’re not alone in this! Our team as well as many other security researchers and vendors are working constantly to build a safer web. Get on board!

my comment does not show
As a cybersecurity expert, many things are wrong about this.
The limitations are so severe, on my website/game/interactive video, I can’t even play a sound without a user clicking first!
(The worst attack is probably download-bombing, taking up like half the hard-drive)
“Downloading” refers to reading, and then your browser (i.e. chrome,firefox,etc.) executes that code.
It is never saved as a file except RARELY in temp folders, and can still not be executed from there.
It seems like marketing skipped over security here.
Hello, Chrome is always in dark mode and any attempt to reach the settings results in an “Aw snap” message. I reloaded the application and it worked to a few minutes then back again. Not detected by AV products. I’ve had to abandon Chrome and lost a lot of information. Any idea of what this is and how to get rid of it?
Is “url.js” a real virus ? I am getting mixed messages from my AV tool.
Appreciate all the useful and shareable information!
Thanks for the post very thought provoking and frightening,if the hackers win and make the internet totally useless won’t they defeat themselves and destroy there own money stream
Hi, quite interest reading. But disabling in chrome does not have any effect. Malware bytes application does not capture this kind of malware. some sites redirect for one or two redirects and some continuous websites.
Please give router setting solutions so that every device of internet access need not be set to safety. hope to receive reply
you CAN’T SECURE ANY device on this planet ….EVERYTHING IS HACKABLE
finally you received your reply
hey. nice. update.

Advirus is malware
I can say that my problem is 90% solved after reading your blog now I just need to follow these instruction to sort out the issue. Thanks for sharing.
son opened a file from an email and then clicked on invoice and was a java now my files in documents etc have been changed some are ac files for my music etc.. any advice?
Hi David! We can’t help with specific situations, because we don’t handle malware removal for individual cases, but you can check out these forums and you’ll most likely get help there: https://heimdalsecurity.com//blog/best-internet-malware-forums/
Now I don’t know it anymore?
Hi Steve! In this case, I think the best approach is to contact Tripod directly and ask them if this has happened in the past and what options they provide to eliminate the malicious code. Without knowing all the details and going through it, we can’t go into more detail. Good luck!
I know of a security vulnerability in cordova applictions due to the android intent filter system. An iframe would download a malicious htm file and then also execute an intent on the cordova app. It would pass the downloaded malicious file’s location as an argument to the cordova app through the intent mechanism. The cordova app would then execute the malicious content upon receiving the intent. Are there similar ways of attack on browser systems – I know chrome can open certain applications automatically using a similar intent-style system?
Hi Andra. Thanks for your swift reply.
I am interested in both actually! I was just thinking about mobile apps when I posted last which is why I provided the cordova example. But I would be very interested to hear your opinion on both scenarios if its not too much trouble. I am a software programmer and I want to take security seriously.
If you have any other specific questions for the team, I’ll be sure to pass them on and get back to you with a hopefully helpful answer.
Thanks very much! I will get all over it 🙂
Very helpful post. Thank you.
So glad you found it useful! Thanks for reading the blog!
