When malware strikes: How to clean an infected PC

Lincoln Spector | May 31, 2013
Snuffing out viruses and malware is serious business. Here's how to diagnose, treat, and protect an ailing PC.

F-Secure doesn't offer a special USB utility. If you want to move a copy of it onto a flash drive, you'll have to download and run the Universal USB Installer. In Step 1, you'll find F-Secure Rescue CD near the bottom of a very long list. I suggest you go straight to the bottom, and then look for it while slowly scrolling up.

8. Protect your newly disinfected PC
When you're satisfied that your drive is clean, try rebooting into good old Windows. Then uninstall your old antivirus program—it has been compromised.

Of course, you don't want to stay unprotected. Reinstall the program and update to the latest version, or (if you've lost all faith in it) install a competitor. For more information on how to choose the best antivirus program for your needs, check out our full rundown—with empirical testing—of the best security software available today.

Because when it comes to malware, a byte of prevention is worth a terabyte of cure.
