windows stuck in login loop
Posted on 2006-06-27
I have customer running Windows XP Home, upgraded to SP2. He recently went to a web site and got a trojan cusing his computer to get stuck in a login loop. The computer boots to the login screen and when he selects any user login, the computer acts like it is loading the user settings, but it returns back to the login screen.
I have run Xoftspy to detect any spyware but it did not detect anyting. Unfortunately I cannot update the trojan adatabase file since I cannot login in ruinning full windows.
I can boot into safe mode OK. I checked to see if the registery entry for userinit.exe is pointing to wsaupdater.exe. It is not. There is no file wsaupdater.exe on the computer. The registry entry is c:\windows\system32\userinit.exe. The userinit.exe file is a 24K file dated 8/4/2004.
I am reluctant to perform a windows reinstallation since I have had problems in the past with some applications not running properly after the reinstall.
What recommendations do you have? Thanks in advance.
