Last night I turned on one of the computers. AVG Free suddenly popped up warnings that files were being infected with the parite virus. AVG couldn't deal with it, despite detecting it. It kept telling me that the vault was full and I couldn't move any more infected files to it. Only choice was to delete them. And I'm talking about the main apps' exe files that we use on this PC such as Firefox, Outlook, Office, and even AVG Free itself. I found some supposedly virus removal tools at the AVG Free and Bit Defender websites. I'm currently trying to clean them up but without any success. The virus is resident in memory so anything that's cleaned gets reinfected. 3 times now I've run the tools over the computer. I created a DOS boot CD with the tools on it. Booted off that. But that won't work as the tools are win32 apps... So, it looks like I have to reformat the HDD. Luckily all of the data that we have is stored on 3 other HDDs on the machine. I shall disconnect them before I start the rebuild and make sure that the anti-virus program is up and running with the new Windows install before I reconnect them so they can also be scanned. What is it with these sickos who deliberately set out to destroy people's hard work? They'll never meet them nor see what they've done. Are they down there with the likes of the psychos who deliberately hurt people and take pleasure in doing so?
