Spywareguard / CRMLOG

Hi there, I'm new to this forum so appologies if this post is in the wrong place, I'd appreciate a redirection if approporiate.
I've installed Spywareguard, amongst other tools, to try and erradicate a problem and at first reboot I got the follwowing many times:
NEW BHO DETECTION ALERT
On 09:54:44 10/14/2006 a new BHO installation attempt was detected.
BHO: {839A51D3-A725-49D3-997E-666CD253907B}
ProgramID: n/a
File Location: C:\WINDOWS\Registration\CRMLog\bvbar.dll
User Action Taken: REMOVE BHO

I clicked remove to no avail. Eventually I allowed it to stay. Can anyone shed any light on this.

Thanks, Pete
