Is the AVG virus online database updater not working?
I ran into the same problem with the free AVG 7.5 that I run on my old computer. You will need to upgrade to the newer version. They do still have all the updates and support on the new one. The only problem there is that you will need Windows 2000, or XP or newer to download the new AVG. It won’t work on Windows 98, 98SE or older. This is from the AVG website. “End of 7.5 version support Support for AVG 7.5 products ended on April 30, 2009. This support covers all home and SMB/enterprise solutions, and includes all updates and 24/7 technical and sales support.
