i do not think your software does. mind you i am using an evaluation copy demo i downloaded from the site, but i found something Very suspicious that TDS-3 did not detect.

ill first give a bit of a background. i leave my comp on 24/7, so about a week ago i come to my computer and it says. "nortons has encounted a problem and needs to be uninstalled". so then i go to uninstall nortons, and thus begins my problems. nortons wouldnt uninstall correctly. so then i go to manually delete the registry keys it made... but i discover i cant use regedit, because "registry editing has been disabled by administrator". i have been using this system since novemeber when i reformated, but i couldnt recall using regedit since then.

when i saw that message, i Instantly thought of a virus. i had read on this forum about operation guard, or some viruses shutting down anti virus software.

i looked at my Task Manager, and the Only thing that looked out of place was something called Spoolwp.exe. i have been trying to find info on it using google, but nothing came up. i got very suspicious about the file because it would be using 30mb or so of memory, which is HIGH for something i couldnt find anything about on google.

so to make a Loong story short. a few days ago i ran a Full system scan with tsd3 and nothing came up. i got a VBS script that same day, and Unlocked my registry.

this evening since ive had some time, i decided to search through my registry for SPOOLWP.EXE to see what i could find. well as it turns out, i found several times and under something called TORVIL. that sounded strange so i searched google and it was a WORM. oddly enough, this is one of the first things that comes up about it.

i tried to delete the spoolwp.exe file by changing the name. now when i startup something pops up saying windows could not locate spoolwp.exe when i restart. anyway, here is the key.

so does TDS-3 detect the TORVIL worm? ???

Hi TDS3 does detect the worm Torvil.D. You may have a variant. If you can find the file please zip it up and send to submit@diamondcs.com.au

You can manually download new definitions (radius database) from here: http://tds.diamondcs.com.au/index.php?page=update Pleas follow the instructions on tha page.

After getting the latest update please do a full scan in safe mode, safe mode can be reached by pressing F8 a few times after your BIOS loads and before windows starts to load. In scan control enable all the scan options and then scan all physical drives. This is a very deep scan and will take some time.

mooseboy84,
You might want to consider getting a registry monitor, a good one would have alerted you to the entry being added

There are several threads on wilders discussing the merits of the different ones
Have a look at Registry Monitor Comparison (http://www.wilderssecurity.com/showthread.php?t=32823)
Another thread that might be useful is Security that you use and its purpose (http://www.wilderssecurity.com/showthread.php?t=62972)

I wonder if Wintasks 5.0 would find it and show all it's DLLs?

Copies itself to %Windir%<filename>.exe.

where <filename> is one of the following:

spool<random letters>
SMSS<random letters>

For example, the worm may copy itself as C:\Winnt\spoolax.exe.


Repeatedly opens and closes a command window with the following characteristics:

Title: <filename>
Message: <current date and time> xExec %Windir%<filename>.exe


Creates the file, C:\Torvil.log, which is a text file. This file is not viral by itself, therefore, Symantec antivirus products do not detect this file. Manually delete it.


Adds the value:

"Service Host"="%Windir%<filename>.exe"

to the registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

so that the worm runs when you restart Windows.


Adds the value:

"Shell"="Explorer.exe %Windir%<filename>.exe"

to the registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon


Creates the subkey:

OneLevelDeeper\TorvilDB

under the registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\
explorer\Advanced

and adds the following value to the subkey:

"TORVIL"="<filename>.exe"


Creates a Mutex "Torvil", which allows only one instance of the worm to execute in memory.


Registers its process as a service if the current operating system is Windows 9x.


Runs itself as the service, "Torvil," if the current operating system is Window NT/2000/XP.
