Install, update and run = Avast = 4 Home Edition - Free antivirus software - free virus protection for home PC: - full-featured antivirus package designed for home usage.(FREE) = http://www.avast.com ,

and then uninstall AVG.

An important thing to keep in mind, regardless of which anti-virus, anti-malware, anti-spyware and firewall you use -

( http://www.microsoft.com/athome/security... ) is to keep it UPDATED, just as it is important to make sure you have all windows critical and security updates +

Note: The way I have mine set is to only notify me that updates are availiable, but to not download them automaticaly. Then I can check to be sure I get just the ones I want. I then click on "custom", and after the updates have been downloaded I look them over to see which ones I want, then disconnect from the net, disable firewall and anti-virus program, and then install the updates, and then re-enable the firewall and anti-virus programs before reconnecting to the net. = http://support.microsoft.com/kb/306525
