Hi Elvandil, thanks for replying. I have tried the autorun but I couldnt find any blank 'image path' - am I looking for the right registry here? I have tried to uncheck all startup program in autorun under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run , C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Startup , and HKCU\Software\Microsoft\Windows\CurrentVersion\Run under Logon tab but no luck. I dont want to go further unchecking other fields and do a trial and error thing because Im afraid I might crash my system. So I decided to post my problem here for some expert advice. How and where can I find the ' ' thing in autorun if it is blank? Theres no blank Autorun Entry when I run autorun.exe. There are 3 entries however that have 'File not found' entry in column 'image path'. I already tried to uncheck them and reboot, but the message is still there so I check them again. Please tell me what to do, I appreciate it :-)
