    I tried downloading this automatic spyware removal download, but the Security Tool pop up won’t let me clean my computer, it won’t let me download anything to get rid of the worm viruses. What should I do, I can’t use my computer because of this Security tool Fire Alert. Every time I try using my start menu to delete the Security tool Alert, it keeps asking me to clean it and then i have to purchase it.
