I think I might have a virus on my computer.
I was just on MatchCut and YouTube, and all of a sudden everything slowed down so badly that I had to restart.
When I did that, and the system booted back up again, there's a new program on my bottom right taskbar - its icon is a blue and white shield, and it is called "Antivirus System PRO".
It won't let me do anything, claiming that everything I try to open is "infected".
I can't even get my control panel open to manually remove the program from my computer.
I'm stumped what to do.
