This program comes in many variants. Antivirus 2008, Antivirus 2009, Total Security, ect. The best thing to do if it initially pops up is start Task Manager "ctrl+alt+del" find the "Applications" tab and end the Internet Explorer Window that it popped up. If you click anything else, then you have installed it. These variants are able to bypass the antivirus software, probably because they are malware and not viruses. This program installs numerous malware programs onto your system, making it very difficult to remove. Like the posting above stated, this is not a legit company, DO NOT GIVE YOUR CREDIT CARD INFO! I run into this problem all the time at my job I work at a college, and have chosen to just backup all the files and do a system restore. Now I have been successful running a couple of programs called "Superantispyware" which is free and another called "Prevx" which will cost $29.99 but this solution will be a little time consuming, and I don't have time to run these programs at my job because I usually have a line of students at my door.
