Hi, new to the forum as a poster, but have fixed a couple of problems before following the advice given others in these threads, keep up the good work!
I am running XP Home, ver 2002, SP3. My current problem has to do with the userinit.exe not self terminating. This is located in C:/windows/system32. From everything I have researched so far, I undrstand that this is a vital program for Windows to startup and logon. The problem is that the program does not self terminate after startup, then blocks access to the internet and email servers. Terminating the process in task mananger eliminates the problem, and thats the work around I am using right now until I can figure out what has modified the program. When I pull up the properties on userinit.exe, they show that the program was modified on Oct 7 2008 at 11:50:39 AM. I know for a fact that my computer was on at that time, but I was in town, taking a clients car to the shop, when I returned home at 2:00 PM, I first detected I had a problem and the hunt was on. Avira is the only software that detects this problem, and it calls it TR/agent.agga. I was thinking about replacing userinit.exe with a clean copy from C:/I386, but I want some more advice before I mess with this critcal program.
So there is my sad story, what do you think?

Try running the System File Checker (SFC).

Thanks Budapest, I ran "sfc /scannow" from the "start"..."run" menu, Windows checked all of the protected files, automatically replaced the modified file, and all is well!!! I ran Spybot, Avira, Ewideo, Malwarebytes, and checked my HJThis logs. I also checked the properties of C:\windows\system32\userinit.exe and they are back to normal. I AM CLEAN!
