Backdoor.tidserv removal tool

Runing XP SP3. Norton Internet Security 2011 came up with warning:

"volsnap.sys.vir contains threat backdoor.tidserv.inf"

Status "manual removal required".

Risk: High

 

Infected file is C:\Qoobox\quarantine\C\WINDOWS\system32\drivers\volsnap.fix.vir

 

Using option "remove this file" resulted in something like a "not possible" message.

On this page http://www.symantec.com/security_response/writeup.jsp?docid=2008-111113-1112-99&tabid=3

Its says to run Norton Power Eraser. This took a long time to reboot, did an long scan and reported no threats.

 

Then I saw another page http://www.symantec.com/security_response/writeup.jsp?docid=2010-090608-3309-99

about the removal tool. I downloaded this tool, but after running it get the error:

 

"pre-boot operation failed, unable to continue".

 

I cant figure out how to manualy remove the threat. Can someone help?
