My computer (XP SP2) is infected with malware that pretends to be User Account Control. Help!
Here's a screenshot
of a message that pops up when I start up the computer or open a program. (the memory processes it cites are different each time.) If I press allow, it goes away. If I press allow too many times, the computer freezes up (and I have to restart.) If I press "scan system" it pretends to scan my system and find viruses, and then it says I need to purchase security software. And then there's an (uncloseable) window that asks for my address, and then credit card info. (And I have to restart.)
I've scanned my system with Malwarebytes, AVG Free, and Norton Free, and they don't catch it.
I've tried looking for a solution on google but can't find one.
I think the thing came from an ad on The Pirate Bay.
How do I take care of this?
Incidentally, not one but two nasties appeared on my system while I was visiting The Pirate Bay. I got rid of the other one with the help of myantispyware.com, and hopefully I'll get rid of this one with your guys' help. But now I'm wondering: what if there's more than two? Might there be undetectable
spyware lurking on my system? Is there any way to check for that, besides programs like AVG and Malwarebytes?
