I downloaded something that was fake and it put this virus on my computer that has stopped the internet, a million ads come up and malware/virus notifications which im sure its making, and its made it almost impossible to do anything on my computer. It restarts randomly, and programs randomly close. Spyware doctor, zone alarm, and NOD32 anti-virus have failed to stop it. It's infected multiple files that start in is such as isnotify, issearch, ect. It has also locked me out of task manager, saying the pc administrator has locked me out while im the only one. I cannot use my computer. Help!
