I had the same problem on my 32 bit XP Pro setup, however, with HKCR\.com. Assuming it to be a false positive, I told SuperAntiSpyware to ignore it. Then I checked the registry and found that it was indeed a false association as .com was referred to as an exefile and not a comfile. An easy way out (which I used) was to download a fix from here: http://www.dougknox..../file_assoc.htm I enclose the screen shot of the opening page, which speaks for itself.
Worked for me .. as SuperAntiSpyware keeps quiet about the false association, at least for now.
p.s. edited above link (removed trailing '.' to make it click-able). And, ran another scan and no problems, so it seems the fix took care of a file association which indeed was broke (imo).
