Was browsing internet today when windows started popping up left and right, it was like the mouse became super sensitive, cause whenever i moved it, a new window opened. so, i figured it was some sort of trojan and tried scanning. well i couldn't get to the scanner cause of everything opening randomly. then, the computer turned off. i rebooted into safe mode and tried system restore. upon restart it informed me that the restore could not be carried out. so i rebooted into safe mode again retried more checkpoints. nope. i tried the scanners in safe mode, they wouldn't work. i tried downloading avast, after installation it said was restored wrong or something andthe computer promptly turned off. it seems like someone is controlling my computer. everytime i try to fix it, it really starts acting up. the only thing i can think that happned, i downloaded a song off limewire. but the cdomputer was fine for awhile after that. Any help please? i do not know what to do!
