avg updating virus definitions-28

An up-to-date virus database is a critical component for any security software, on which the detection rate directly depends.

To ensure your AVG Antivirus provides full protection at all times, the AVG team analyzes new threats and information regarding new viruses, releasing updated virus definitions and antivirus improvements periodically.

Of course, if your computer is severely infected, you may have to resort to an Antivirus rescue CD from your favorite security company.

Fortunately for most of us, many of the antivirus companies provide offline virus definition signatures so you can download them from another computer and then manually install the updates on computers with a limited or no internet connection at all.

While it might be fine for most users, letting your antivirus package update itself every few minutes isn’t great if you have a very small limit on your internet connection or it’s not very fast and constant updates are eating up your bandwidth, such as when using a mobile dongle on your laptop for example.

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constantly offline and not connected to the internet for long periods or at all, the virus definitions will get badly outdated in no time and your computer becomes more vulnerable.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.

They need to be as up to date as possible to have the best chance of removing the threats.

This option is available in the tray context menu of AVG and ensures that the security software compares scan results to an up-to-date signature database, so as to detect both known and recent threats.
