I have recently noticed the above running as a service. I don't remember installing it so am a bit concerned. There are 3 other versions of this all starting with wintools.
Is this a microsoft program - I think it works with IE.
I have run 3 virus scanning programs, all have turned out OK apart from AVG which consistently finds the startpage virus even though it has been healed. Other virus scanners used are Mcafee free scan and trend micro scan.
