Cannot locate virus file

I am running XP Pro SP3 Fully updated with CIS 5.9.219863.2196 database v 11248.
For some time now CIS has detected the following: Rootkit.HiddenValue@0 HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Extensions\CmdMapping{c95fe080-8f5d-11d2-a20b-00aa003c157a}
The program will not remove, quarantine or submit it. It says, Not a suitable action for this threat (or something similar)
I have scanned with GMER, Malwarebytes, Spybot, and TDSSKiller but nothing is found.
When I type it into Google it appears that quite a few people have come across it on their machines. Some say it is a virus, some say it is not a virus but that it is the ALEXA toolbar. I have never had the ALEXA toolbar but I did have the Ask toolbar which was uninstalled about 2 years ago.
The computer behaves normally so I am inclined to think that it is a false positive.

I have tried to locate the file so that I can report it as a false positive but I am unable to locate it on the system.
Comodo flags it up each time I do a scan.
Please can someone tell me what action to take to prevent this happening?

Best regards

Hello jamarisk,

How is the investigation going?
Have heard nothing yet!


Have still heard nothing about the proposed fix to my problem originally posted January 12.
Is the solution, days, weeks away?
Please can anyone tell me if there is anything that I can do to help expedite the solution?

Regards, patiently

Hello ,

The issue has been verified and a fix will be available with upcoming version 6 of Comodo Internet Security which will have an improved rootkit scanner module.

Thanks and regards,

Many thanks FlorinG
