Runs on All Windows Versions



AVG free edition includes AVG Email Scanner, which checks your emails for any nasty viruses. AVG Resident Shield, which checks for viruses as files are opened and executed.
Also it will prevent you from opening or running an infected file.
Also there is AVG Virus Vault, a place where any infected files are isolated so they cannot cause any damage to your PC.
The inbuilt scheduler is basic, but does the job. But trying to update can be hassle as AVG keeps trying to get you to upgrade to the paid version, which I guess is understandable.
The only real problems is that the scanning process takes a while and there is noticeable system drag, but you can easily adjust that in the options.
I would highly recommend AVG free edition if you need a quality scanner and don't want to spend the money on a regular paid version. B-)
A great piece of freeware
:-D
I would certainly recommend this over spending way to much on Norton or other antivirus software where you must pay an unrealistic amount.
It's easy to use and is always updating with new virus signatures to protect against the latest viruses, so for now I see no point in using any other version! :-P
