| My Symantec antivirus detected an instance of the W32.Spybot.UBH on my
| machine, however, it could only quarantine it, not delete it altogether. I
| have been following the instructions on Symantec' website
| (http://securityresponse.symantec.com/avcenter/venc/data/w32.spybot.ubh.html)
| which, at one point, require deleting
| HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\ENUM\ROOT\LEGACY_SVKP
|
| Unfortunately, RegEdit just won't allow me. When I locate the key, and press
| delete, I get an 'Error Deleting Key' popup message. Any suggestion? As
| always, thank you in advance for your ideas.

Quarantining a file is good practice in case a file is deemed to be a falsely declared as
being infected. You can always dump the NAV quarantine later on if it truly infected.

Please read the following URL -- http://vil.nai.com/vil/content/v_135434.htm

Go to; start --> run
execute; services.msc

Look for a service called; SVKP

If you have it do the following...

Use the Resource Kit utility, DELSRV.EXE, and execute; delsrv SVKP
Reboot and then scan the system using the following Multi AV scanning tool.

I posted the DELSERV.EXE utility in a ZIP file...

Post Subject: DELSRV for Hacktool.Rootkit
Posted in: alt.binaries.comp.virus

Start with the McAfee module in the following Multi AV Scanning Tool...

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

It is a self-extracting ZIP file that contains the Kixtart Script Interpreter {
http://kixtart.org Kixtart is CareWare } 4 batch files, 6 Kixtart scripts, one Link
(.LNK) file, a PDF instruction file and two utilities; UNZIP.EXE and WGET.EXE. It will
simplify the process of using; Sophos, Trend, Kasperski and McAfee Anti Virus Command
Line Scanners to remove viruses, Trojans and various other malware.

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.

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.
