So the antivirus trial or subscription you had has expired, and now our computer is giving you messages like “YOUR VIRUS PROTECTION HAS EXPIRED! RENEW YOUR SUBSCRIPTION NOW OR EVERYTHING WILL CATCH FIRE! AAAAAAHHHHHH!!!!!” Once that happens, you have a choice: pay to renew what came with your computer or find a replacement.
But don’t just install the first thing that shows up in Google. A little research can help you make a decision that ensures your computer is protected – and it might protect your wallet, too. There are two main sites I turn to for information on antivirus products: AV-Test and AV-Comparatives. Both are independent organizations, not connected to any vendors of antivirus software, who run comprehensive detection, cleaning, and usability tests.
