Hello there,
due to some malicious software run on my computer I may have lost some
windows settings. I cannot bring up task manager using ctrl alt del keys,
instead a list of tasks appears in DOS mode and disappears also suddenly.
Please help me to bring up Task Manger in Windows.
Thanks.

You can right click on the Taskbar and select Task Manager

Click Start, select Run and type taskmgr then click OK

Regards
Mark Dormer

Are you able to run regedit or msconfig from Start | Run?

Yes, I can run msconfig and regedit. I have also the taskmanager option when
I right click on the toolbar but the same happens. But don't know what to do
next. Please suggest.
Thanks

Pramit,

Open Regedit.exe and navigate to:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File
Execution Options\taskmgr.exe

Export the key to a REG file, and post the contents here.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File
Execution Options\

I this any symptom of something else ?

Pramit,

First, it's taskmgr.exe. That key will not be present by default. It's good
that you don't have that registry key. See if these cleaners can help you.

1. Ad-Aware
http://www.lavasoftusa.com

2. SpyBot S&D
http://www.safer-networking.org

3. CWShredder
http://www.intermute.com/spysubtract/cwshredder_download.html

Update 1 & 2 before running a scan.

Clean-up Windows Startup:
http://windowsxp.mvps.org/startup.htm

Then, run a full system virus scan with fully updated definitions. Try Trend
Micro's Sysclean package (free), it's capable of eliminating keyloggers,
trojans etc.

Thanks Ramesh,
I have run SpyBot and Ad-Aware already before but found nothing. I found in
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\
3 folders namely NonEnum, Ratings, System instead of 'explorer'. In the
'system' I found several value names including one as 'Disable TaskMgr'.
Should I delete those?

Pramit,

The presence of "DisableTaskMgr" value under the key you stated, has no
effect. This is a per-user Policy, whole correct location is here.

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System]

But this causes the error message "Task Manager has been disabled by your
administrator" when you open Task Manager. So, I don't think this applies in
your case.

Have you tried Trend Micro's Sysclean package already? Also, download
HijackThis from http://www.spywareinfo.com/~merijn/ Generate a log using
HijackThis and visit any of these forums below to post your HijackThis log.
The experts there will guide you how to remove the malware from your system:
