i tried downloading puff the magic dragon for my brother using limewire. after the download was complete, i opened it with itunes, realized it was a virus, and i began getting popups of porn and the like. now about every 10 minutes or so, i get a blue screen, my computer crashes and restarts. ive tried to start in safe mode, and i had absolutely no internet connection. i also get a pop up everytime i sign on that says iexplore.exe is requesting permission to access my computer which i cancel everytime. any ideas as to what i can do to get my computer to stop crashing? the file from limewire was already deleted completely from my computer, so i dont know what the problem is.
