Keep My Computer Safe from Cyber Threats that Target Home Users
Find out how cyber criminals are trying to infect your PC
You know that sinking feeling you get in your stomach when you’ve misplaced your wallet and think you’ve lost it?
Even if it lasts for no longer than 10 or 30 seconds, your mind will start building scenarios at an incredible speed:
- I’ll have to cancel my cards!
- I’ll have to get my ID reissued!
- How much cash was in it?
The fear is palpable. The damage is tangible. You know what can happen if you lose your wallet, which is why you go out of your way to keep it safe.
Change Your Perspective
But you just don’t get the same feeling about the information stored on your computer. It’s natural not to, because they’re pixels on a screen, not money in the pocket. Because it’s data in the cloud, not documents in a briefcase.
The problem is that we increasingly see our money in the form of pixels which we use to shop online, and our data and work as documents in a cloud folder. Does that make them less valuable? I bet you’ll agree with me that it doesn’t.
The media talks a lot about cyber attacks, but also about their circumstances and consequences. And they have good reason to do so. But here’s the issue: “DDoS attack”, “data leaks”, “compromised credentials”, “CryptoWall 4.0 ransomware” – most Internet users usually ignore security jargon like this. To them, and maybe even to you, it doesn’t mean much. And there’s no one to be blamed here. After all, not everyone has the background to understand why these attacks are dangerous and why they should react to news like this.
You’ll often find information about threats that target companies and attacks directed at home users mixed together. So it’s understandably difficult to tell which ones you should worry about.
That’s why we decided to do something about it. We’re set on making it easier for you to figure out what you should protect your system against.
The 6 Most Common Cyber Threats that Target Home Users
(and What to Do About Them)
What is it?
- One of the most evolved forms of malware on the market;
- A type of malware that can encrypt all your data and make it unusable;

What ransomware can do to your system and data:
- It can infect your computer if you click on an infected banner, if you download and open an attachment from a spam email or if you end up on an infected website;
- Encrypt all your data, including file names or information stored in your cloud accounts synced on the PC;
- Ask for ransom to provide the encryption key (around $500, but it could be more and, very rarely, less);
- Harvest your data (system information, email addresses in your agenda, etc.) and send it to cyber criminal servers to use it in future attacks;
- Destroy your data, it the encryption key was not downloaded correctly and won’t work when trying to decrypt your data;
- Hide from being detected by antivirus products because of its communication mechanisms;
- Enlist your computer in a botnet and use its resources to launch attacks on other victims.
Give me an example: read about CryptoWall 4.0 – new, enhanced and more difficult to detect.

- It can cause financial, social or emotional damage by depriving you of money, goods or by making you go through distressing situations;
