Security Tool pops up even though we have not downloaded or have this programme - It happens on start up - cannot access anything else - encourages me to enter CC details etc. "Skype is infected with worm LSAS. Blaster. Keyloger...Skyper is trying to send your credit card details..."also msnmsgr infected with LSAS - never seen anything like this before.
Desk top comes up then disappears.
Cheers
