No surprise. Must be one of the trojans. What they normally do is lock your Windows and tell you your PC is suspected of having illegal content, punisheable by this and that, but if you send a modest sum, you can have the code to have it unlocked.

Of course paying is useless, and the way to go is to either seek help at dr.web.com (they have a free help service for that), or get aroung Windows by running an alternative operational system from an external drive and clean the autoexec.but and config.sys files, where these bad germs normally roost.
