I have spywaredoctor which I use daily. It found the following today:

Trojan-PWS.Tanspy - Threat Details

              Beskrivelse:Trojan.PWS.Tanspy will install itself on to an 
              infected computer as a Browser Helper Object (BHO). This 
              Trojan will then be activated each time an instance of 
              Internet Explorer is launced and will attempt to steal 
              passwords.

The first thing I would suggest that you confirm the detection is good.

What is the infected file name, where was it found e.g. (C:\windows\system32\infected-file-name.xxx) ?

You could also check the offending/suspect file at: VirusTotal - Multi engine on-line virus scanner and report the findings here.

thanks pal

I’ll remember that!

No problem, glad I could help.

Yes the VirusTotal resource is very useful.
