Keep getting 1 infected registry key only with MBAM and nothing with Avira or Hitman-Pro MBAM Log says: Registry Keys Infected: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\Notepad.exe (Security.Hijack) -> Quarantined and deleted successfully. It recurred 1 time after reboot. However now it seem to be gone. Is it a false positive or real Security.Hijack infection? Thanx in advance.
