Related, sort of.
My PC recently picked up a virus from a site I checked out on TC ... back then I checked every first time poster's site if they listed one or linked one.
I immediately got a seemingly authentic virus scan that turned up 34 serious problems in around 60 seconds, fortunately I knew this was not the real deal, but it was quite crafty as it used Windows security sheild notifications, etc. It looked quite real. And it likely gets many people to in a panic act immediately.
Turns out it is Vista Home Security 2011 virus. Basically it is set up to try and get you to take the bait in a panic mode and buy the fix. And if you do, they have your CC info and who knows what else since you have to register to their psuedo Vista security.
I could easily have taken the bait, but I had enough of a feeling that it was not "right."
This was several weeks ago, and I thought I had purged my PC of the affected files. But it just turned up again 2 days ago.
