Have an XP Pro SP3 with malware. It has disabled taskmgr, regedit, IE, spybotsd at least. Malwarebytes removed four items (trojans and downloaders). GPedit will run, but changes to Ctrl-alt-del; and disable regedit will not stick. Common tricks to run Reg delete as a vbs script or in CLI mode to del related keys will run, but does not help. Seems I can not start in Safe Mode either. The hosts file was not hit.
1) Any ideas what this malware is and 2) how to clear it from this system?
