I just wanted to give everyone the heads up on this. I have spent the better part of two days getting rid of this. It popped up on my late husband's computer after someone else used it. It also goes by the name Internet Security 2010, and Vista Internet Security 2010 and probably others as well. This is a fake antivirus that tries to get you to believe your system is infected and then wants you to buy the full product so your system is protected. It got so bad on the computer that this morning, I couldn't even open Internet Explorer or Mozilla Firefox. I ended up running Spybot Search and Destroy three times and it finally took care of it! I was told by the person at the local computer support here that it comes from corrupted myspace ads and also from corrupted facebook ads. I wanted to put this here so others can be aware of this. I hope no one else has to deal with this!!! It's a pain!!!!!
