"Microsoft Works Imaging Server from Microsoft Corporation ()". I am wondering why would a microsoft program be considered unverified?
Who says it was from Microsoft, the fact it says "unverified publisher" almost certainly guarantees its nothing at all to do with Mircosoft.
Its very very easy for something to pretend to be from someone its not on the net, why do they do this, to con the unware into downloading their malware !!!
I think you should post a HJT log at one of the malware removal forums for their experts to look at.
You can either google for "ASAP" and pick the cleaning site of your choice or follow one of these links

What the tech Please note all the forums are busy so it may take a day or too before they get back too you, also you should ONLY post your HJT at one forum.
