We hope you always keep in mind Krebs’s Number One Rule for Staying Safe Online: “If you didn’t go looking for it, don’t install it!”
That means: Unless you purposely set out to put a new program on your computer, don’t click “install”, “run” or “continue“.
This rule is increasingly important in a world where the malware is being socially engineered to cause you trouble. Take this recent case from the F-Secure Labs where a web exploit can tell if you’re using a Windows, Mac or Linux PC. Once installed it knows exactly what trojan to install and it connects back to its source to find more malicious code.
How do you avoid getting bad software trying to install itself on your PC?
Kreb’s Number Two Rule will help you with that: “If you installed it, update it.”
The software on your PC is as only as secure as its latest update. Your job is to make sure that you keep up with the updates for your system software and all the applications you use. Our free Health Check makes that easy on Windows PCs.
Of course, we also recommend that you run updated Internet security software. Our Browsing Protection will block most of the sites with harmful payloads. You can try F-Secure Internet Security free.
