i know of this problem all too well. i have worked on 20 + machines that has gotten this very annoying 'scanner'. its managed to slip past the local school system firewall , county courthouse and infect tons of home users - myself included! myspace, certain lyrics sites, **** sites etc greatens your chance of getting it but anyone can pick it by JUST BEING CONNECTED TO THE INTERNET. i done a fresh format and reinstall of xp pro on a personal machine (sp3), anti virus , etc and all i did was plug the cat5 cable in and got it. and im behind a router to boot. there are actually two advertisement companies behind this which were tied in a lawsuit over it. the program 'scans' your computer in hopes that you will buy its product which is anywhere from $50 on up. then that company charges you monthly, usually around $80-$100. i have had two customers purchase it. the designer of the program is very smart. they have designed the program so when you click on the 'X', that activates it. best thing to do it crtl-alt-del and end the program thru task manager. then, as the above poster stated, download and run malware bytes. awesome program but you have to run it as soon as you see the scanner or it will do no good
