I tried to take a screenshot, but couln't upload from work due to the bars in place...
Sorry for all the swearing by the way, not called for, just got a grilling cus' I shouldn't really have been on here, so many apologies for that.
It happened to me in general section, was just posting as normal & it just jumped in, closed down internet explorer then started with its "pay to update security centre" malarkey.
The filename was: FakeTrojan.av & it infects extension files in user settings folders & spreads into program extension files the more you carry on operating wih it on your system.
The I.T guys here think its when there are multiple users on one server like here, they have closed this loophole it used to get in here, so hopefully won't have the same problem again.
But it wrecked all my settings & paths to files for programmes upon deletion as it actually becomes an extension of a Dorment Standard Windows Security Centre when you're using a Secondary Virus Protection (Norton etc) as your primary Firewall & as previously described, carries on spreading through file extensions.
Clever, but bleak as hell.
Hope this helps.
Cheers,
Amos
