I have a toshiba satellite laptop w a intel core duo 2 processor. it is running windows 7 home premium. And what the problem is that i was using my laptop without any antivirus software and now i have a system tool program popping up saying that my computer is infected and it has 27 viruses. if i try to run a system restore or any program it says it can be opened because a worm in inside of the software. How can i get rid of this so that my computer can go back to running i have an anti-virus program that i can install as soon as it is cleaned out. I just need help getting rid of this program.
