One of the programs I need is Google Desktop. I use it a lot. Now, at work I'm very very good and don't download any other software. Nothing at all.
The fact that AVG has listed Google Desktop as being/infected by a virus makes me feel forlorn. I really want to keep it!
Oh well. I'll wait for the scan to finish, see if AVG can fix and if not then I'll risk a purge and re-install.
