PC PROBLEM C:\autorun.inf -r -h -s and click OK then E:\autorun.inf -r -h -s OK and so on for all affected drives. (After that I found a notepad with something lettering,then wht I do?can I delete them ? ) Finally check the volume root of each drive for autorun.inf file. Is that file present in any drive? If so, manually delete it. ( How ?) then do this:- 1. You have to tell Windows to show hidden and protected system files first.( How.... ?) 2. Then you should search your computer for all instances of files with the name autorun (ANY extension) and delete them. DO NOT DOUBLE-CLICK on discs that have any such files because you will again be infected! 3. Launch regedit - but make sure u backup your reg. first... a ) Find the key: HKEY_LOCAL_MACHINE/Software/Microsoft/Windows NT/Current Version/Winlogon and check the value of the parameter Userinit. This should read C:\WINDOWS\system32\userinit.exe, nothing more. If Windows is installed on another disc, then, of course the disc will be indicated. b ) Completely delete the following key: HKEY_CURRENT_USER/Software/Microsoft/Windows/Current Version/Explorer/MountPoints2. After deleting Mountpoint2 it works fine,but when I restart the computer,the same prob. occure
