Have you created and scanned with the "Rescue Disk"?

My KIS is currently 2011 but, having noticed a brill offer (£22 from the notorious PCW), I have 2012 waiting in the wings until my current version runs out. Nevertheless I'll try the trick you have suggested. Thanks!

You know you can always get the newest version for free if you have a current key.

Just uninstall version you have selecting keep activation data, and then install the new one.

Fake AV's have been known to lurk in "definitely OK" sites - hate the damn things so I always currently use Norton DNS as a first line of defence.

So what?

You still have to click the link in the HTML, then click "Run" or "Save", if you clicked "Save", then go and double click the file, and then click "Yes" to the UAC prompt to allow it to screw up your system.

Yes you are correct, but those fake scans can be really disturbing if one inadvertently opens a link to such malware on what are thought to be harmless sites - to be on the safe side I would close the browser from task manager.
