Despite being a free security tool, AVG Anti-Virus is as good as any paid app. It features a bunch of dedicated modules to protect you from antivirus, spyware, rootkits and spam, and also includes the so called LinkScanner – an extra layer of protection that checks search results and web links to make sure they’re safe.

One of the best things about AVG Anti-Virus is that it offers neat, effective protection while staying silently minimized in your system tray, without guzzling system resources and of course, without constantly bothering you with warning windows or update messages. Being the free version of a complete program, AVG Anti-Virus shows the odd nag screen encouraging you to buy AVG Professional, something which may annoy more sensitive users.
