Running a Compaq with XP that seems to be getting slower and slower. I have Avast, Malwarebytes, SuperAntispyware and Spybot. After running each, the reports are clean, but using Spybot's "Tools", under "System Startup" I find a number of Winlogon files. I turn them off, but after a restart they are turned back on.

Did a little research on winlogons and found that some are indeed necessary, but they are usually in the Windows system files. Also, said winlogons are sometimes a carrier of viruses and trouble. Well, most of these don't seem to be in the system folder. Not wanting to do anything before I'm more confident in what I'm doing, I'm asking for a little help here. Take a look, tell me what you think, and how to get rid of the ones that might be carrying a problem. Thanks, Guys - and Girls

They all show as being disabled for now, but if I reboot, they will show as being enabled.
