Hello, i found a simular topic about this but it wasn't finished. my desktop background is green with a black box in the middle saying YOUR SYSTEM IS INFECTED! in big red lettering and under that it says "System has been stopped due to a serious malfunction. Spyware activity has been detected. it is recommeded to use spyware removal tool to prevent data loss. do not use the computer before all spyware removed." in little white lettering. its not letting me change the display background in properties. im using avast free addition an it pops up saying the computer has a trojan horse named Win32:Zbot-MNS [trj] i tell it to delete permanently but its still there. I would apreciate any help ive been working on trying to figure it out for awile an i cant figure it out. Any help?
