I have windows xp sp2 and norton antivirus 2005 and the virus definitions are fully updated.
Starting last week, Norton pop up boxes have come up saying it detected "backdoor.trojan" in the file " C:\Documents and Settings\Jason Richman\Local Settings\Temporary Internet Files\Content.IE5\V01S1H8Y\cao.exe " and that it couldnt repair it. Then it says it can't quarantine it and than says it cant delete it.
When I run a virus scan in normal and even safe mode, norton doesn't even detect anything. But when I go into nortons "activity log" it lists this file as a backdoor.trojan every time i boot the computer. Ive even turned of sytem restore, manually found the file and deleted it myself, but it always comes back new everytime I boot the computer up.
Since this first happened a week ago, my computer has been acting weird such as: Every time I booted the computer up, a "toshiba power saver properties" box would pop up 50 times in a row and wouldnt stop until I finally disabled it from the startup menu. Also, the windows clock on my taskbar is always wrong and no balloon tips pop up anymore. Lastly, the computer would not let me show "hidden files" until I figured out how to change this in the registry.
Any help would be appreciated.
