Re: SOS: Trojan on XP is not permitting to function any application



I could run AVG scanner and removed 29 instances of trojan
Downloader.UDM for my laptop. Now after that when I logged out, I am
automatically logged out if I try to login. Neither Safe mode with GUI
and Safe mode with command prompt is working. I checked teh registry
entries (through Linux boot) for winlogon which is userinit.exe and
looks correct. Now can somebody tell me:
1. If there is anyway in my situation by which I can copy some files of
windows without logging in as it is not permitted?
2. Anything else which might have gone wrong while removing the trojan
and can be corrected without complete reinstalltion?
TIA

Download MULTI_AV.EXE from the URL --
http://www.ik-cs.com/programs/virtools/Multi_AV.exe

To use this utility, perform the following...
Execute; Multi_AV.exe { Note: You must use the default folder C:\AV-CLS }
Choose; Unzip
Choose; Close

Execute; C:\AV-CLS\StartMenu.BAT
{ or Double-click on 'Start Menu' in C:\AV-CLS }

NOTE: You may have to disable your software FireWall or allow WGET.EXE to go through your
FireWall to allow it to download the needed AV vendor related files.

C:\AV-CLS\StartMenu.BAT -- { or Double-click on 'Start Menu' in C:\AV-CLS}
This will bring up the initial menu of choices and should be executed in Normal Mode.
This way all the components can be downloaded from each AV vendor's web site.
The choices are; Sophos, Trend, McAfee, Kaspersky, Exit this menu and Reboot the PC.

You can choose to go to each menu item and just download the needed files or you can
download the files and perform a scan in Normal Mode. Once you have downloaded the files
needed for each scanner you want to use, you should reboot the PC into Safe Mode [F8 key
during boot] and re-run the menu again and choose which scanner you want to run in Safe
Mode. It is suggested to run the scanners in both Safe Mode and Normal Mode.

When the menu is displayed hitting 'H' or 'h' will bring up a more comprehensive PDF help
file. http://www.ik-cs.com/multi-av.htm
