Comments: couldn't you have said more than just 'Task Manager'? What does that mean? It's gone? You can't open it? It shows processes you don't recognize? I don't understand why some just throw our a log with no information! I don't work through the logs, but occasionally I take a look at what's running.
You have processes that don't need to startup and run in the background: Examples are igfxxpers.exe, DvzIncMsgr.exe, usbshare.exe is for a for a USB sharing switch (Lin-X-Cel) used to share one device between 2 computers- do you have that? jusched.exe is the Java auto updated> you do NOT want that running.
VPTray.exe is VirusProtect Shield System Tray icon, not needed. and on and on.
My point here is to say: No information doesn't give us much to work with. If you system is slow, in addition to malware check, there are processes that do not need to start up and run in the background. You have several of those, but if you tell us nothing, well, other than the malware check, you won't get anything- this is a freebie tip because I'm having a slow day.
And I find that many don't know how to use the msconfig utility to stop unnecessary programs from starting up. There is help for that, but we need to know the problem.
