Hi, I think that my computer is infected with spyware and adware. I've scanned my computer and found that malware and spyware infected it as I downloaded some freeware two days ago. After that I installed a antispyware StopZilla to block these malwares and spywares. When I turn on my computer, Windows XP is running but it shows only the empty desktop and no taskbar. I click mouse and keyboard but doesn't work at all. please, tell me what to do?
