This software was incorporated into the AVG security product range released in March 2009.According to AVG Technologies, the company has more than 200 million active users worldwide, including more than 100 million who use their products and services on mobile devices.It’s also true that if you disable the updates or have computers that are constantly offline and not connected to the internet for long periods or at all, the virus definitions will get badly outdated in no time and your computer becomes more vulnerable.Also, the situation could be that you can’t get on the internet during or after a malware attack to update the antivirus signatures.; this causes the affected systems to either stop booting or go into a continuous reboot cycle.So far, the problem only appears to affect Windows XP, but there is no guarantee that other versions of Windows don’t have the same issue.If you happen to need a bootable CD: my personal favorite is the Ultimate Boot CD (mirror of UBCD 4.1.1 ISO).
Since publishing this article, AVG has offered a free license to all affected users; more about that here.
They need to be as up to date as possible to have the best chance of removing the threats.
Of course, if your computer is severely infected, you may have to resort to an Antivirus rescue CD from your favorite security company.
If AVG detects a virus infection in a file during a download, it will keep the file off your computer.
If you think AVG is incorrectly flagging a file during download, try downloading other files off the same site, as well as other websites, to rule out the specific file being infected.
