However it took some sleuthing to discover the name of the pest and then I could find repair instructions. I'll share the link but in no way does this mean it applies to your machine. The symptom is however eerily similar.
It only took about 10 minutes to fix but a day to find its name.
I have XP Home on my laptop.. I ran AVG and had many Virut viruses.. AVG cleaned/removed... When I went back to logon on I received the windows logon window. I entered name and PW and then it quickly flashed "loading personal settings" but then it said logging off and went back to the logon screen... This happened over and over.. It does the same in safe mode. I am unable to get into the program....
I then installed XP PRO in the same drive...did not partition. So now when I log on I have a choice between either home or pro but I cannot get into home and that is where most of my files are...
Can anybody help. I do have another PC
