Hi All

I am stuck in a login/logon loop in my Fujitsu laptop w/ Win XP Pro, SP2. As soon as I login it goes thru the process and immediately logs me off. This happens in both my account and admin mode. I ran various spyware and virus apps to clean out the PC. A Squared did find a "trojan" run.exe in the Windows/Temp folder called run.exe. It apparently is a trojan.win32.agent.if, so I quarantined it.

System restore does not work either so I posted that to the AumHa system restore forum.

I did search quite a few posts here but I am hoping somebody can give me a solution. If not it looks like a reinstall of XP Pro...

Any help would be greatly appreciated.

I want to make sure I'm interpreting correctly.

You are on the Welcome screen of Windows. You log in to your user account, and as soon as you are logged in you are then automatically logged off. Is that right?

Does this happen also in safe mode?

Hi Orange Blossom

Yes, the PC boots up and goes into the log on screen and then when I enter user name and password, it logs in and then goes immediately into a log off, both in my account mode and admin. This does not happen in safe mode.

Thanks for the clarification there. My thoughts: this is caused by infection or infections, there are damaged system files, or both. So, one step at a time.

First, let's see if we can't get you into normal mode this way:

Boot up into safe mode then click on Start --> Run. Type in the run box sfc /scannow Note the space between the c and the /. Click on the OK button. Just in case have your reinstallation, not recovery, disk handy. The computer will now check to see whether there have been changes to protected system files. If any are damaged or missing, it will either repair or replace them. If prompted enter the reinstallation disk.

When finished, see if you can now boot into windows in normal mode.

Let us know how it goes.

I tried the scannow command from Run but all I got was a quick DOS screen and it disappeared but it had no discernible effect on the problem. I'll keep plugging away...

If you can get in to Safemode try turning off "reboot on system failure"
