Log on looping and my "User accounts" changed

By kindozo ·
My PC is a Toshiba Satellite A355-S6935 with Windows Vista Professional installed. My prblems are in 2 folds: The 1st happened before the 2nd.
1. I installed some windows update and since then my user accounts have changed. My desktop has initializes when I log on, it has changed, "My Documents" is empty but I see all installed programs when in control panel. Guest account is ok but my main accounts has changed totally. I did system restore but "undo" it cos the problem remained.
2. Now I experience logon/logoff loop with my user account. Guest account is not affected though. The interesting thing is that I see all my user account files with no problems when I use safe mode. Safe mode works well but normal mode keeps looping with logon.

I need help recover my PC to do my project work.

Many malware varients effectively HIDE user files...

by SmartAceW0LF In reply to Log on looping and my "Us ...

this is the first thing that comes to mind in this scenario. It can usually be verified by opening the Start Menu. It will also usually be empty. The prospect of getting Windows Explorer to "Show All Files" and then subsequently selecting every necessary file within each folder and choosing to "Show" them can be a daunting one for even the most experienced techs. Fortunately the good folks at BleepingComputer dot com have provided a tool to do this. You can get there by going there and clicking on the "Download" tab from within their site. The tool is the second one on the list. It is called "Show Hidden". A thorough scan by Malwarebytes Antimalware and/or Combofix will be in order afterwards if this is the problem.

Incidentally, all of these tools can be installed and ran in Safe Mode With Networking. And it would be my recommendation to do it in that mode. Finally, should you choose to use Combofix, be certain you download it ONLY from bleepingcomputer DOT com.

There is an excellent chance that once the above is taken care of regarding the scans for malware that the bootlooping issue may resolve itself. Try that and get back with me.
