VirusScan 7 is many years past its end of life and if it was updating until now then it was sheer luck.

I just realised you had entered the word "home" in your header. I had moved this to VirusScan Enterprise thinking that it was that entity. Are you absolutely sure it's the home version?
If so, then that isn't supported either, hasn't been for 6 years or so, and again, if it was updating that was sheer coincidence. There isn't much point in using outdated protection, even if one can get it to update, which is in itself a task and a half, but these older products don't have the capability of detecting and handling many of the newer types of malware.
I strongly suggest that you get a modern product. What operating system and service pack are you using and is it up to date?
