Prob with drwtsn.exe

mgupta · Oct 12, 2008

hi...
I have Windows XP professional.My problem is that task manager and task bar got struck several times and I need to reboot my Pc manually.Although I can access my desktop items.Also when I opened a particular folder in E drive then the window got disappeared after a few seconds.I think there may be some problem with drwtsn.exe
I have regularly updated Kaspersky Internet Security 8 installed and have full scanned my system.Also I have checked for spywares with Spybot and have checked E for file errors with error checking tool of windows.
Plz help me sort out the problem.

Can you check whether the system behaves fine after disabling Dr.Watson? Steps to disable Dr.Watson can be found here:
*support.microsoft.com/kb/188296

By the way, can you download HijackThis from here:
*www.trendsecure.com/portal/en-US/tools/security_tools/hijackthis
Once you download the ZIP file, extract it to a folder and run the HijackThis.exe executable. Now, click the button "Do a system scan and save a logfile" to start a scan. After few seconds, HijackThis will create a log file and open it in a NotePad window. Copy the complete contents of this log and post it in your next reply.

Note: Do not fix/modify anything using HijackThis, if you are not sure about it!

There are some malicious files that need to be removed now! Okay, run HijackThis and click the button Do a system scan only. It will scan the system and display the results. Now, select (put a checkmark) the items mentioned below:

Code:

O4 - HKLM\..\Policies\Explorer\Run: [Altap] tskstsh
O4 - HKUS\S-1-5-19\..\RunOnce: [Set] fuset.exe (User 'LOCAL SERVICE')
O4 - HKUS\S-1-5-19\..\RunOnce: [tscuninstall] %systemroot%\system32\tscupgrd.exe (User 'LOCAL SERVICE')
O4 - HKUS\S-1-5-20\..\RunOnce: [Set] fuset.exe (User 'NETWORK SERVICE')
O4 - HKUS\S-1-5-18\..\RunOnce: [Set] fuset.exe (User 'SYSTEM')
O23 - Service: MySQL - Unknown owner - C:\Program.exe (file missing)

Once all the above entries are selected, click the Remove Selected button.

Close HijackThis after performing the above step. Now, delete following files if they are present in your system:

Code:

C:\WINDOWS\system32\[b]tskstsh.exe[/b]
C:\WINDOWS\system32\[b]tscupgrd.exe [/b]
C:\[b]Program.exe[/b]
[b]fuset.exe[/b]

You need to search for the file fuset.exe as its path is not known. And, you may also need to make Windows to show hidden files/folders, if you are not able to see above mentioned files.

Reboot the system after deleting those files. Download MalwareBytes' Anti-Malware( *www.malwarebytes.org/mbam.php ) and install it. Run a complete system scan using MalwareBytes Anti-Malware and remove any malicious item it may find.

After this, post a new HijackThis log.

Hi,
Do you have this file in your system:
C:\Windows\system32\tscupgrd.exe
If yes, can you scan the file at *www.virustotal.com/ ? VirusTotal is a free online file scanning service, which uses 31 AntiVirus software. Let me know the results of the scan.

By the way, did MalwareBytes' Anti-Malware found anything?

mgupta · Oct 15, 2008

As you said I have deleted this file already from my system, and Malware perform these two actions after full computer scan-
Registry Keys Infected:
HKEY_CLASSES_ROOT\WUSN.1 (Adware.WhenUSave) -> Quarantined and deleted successfully.
Files Infected:
C:\WINDOWS\system32\winamp.exe (Backdoor.Bot) -> Quarantined and deleted successfully.
And the problem still exists......

Prob with drwtsn.exe
