Ok, do this;
Go to this website http://virusscan.jotti.org/
The page will upload this file from your computer and run it through multiple virus scans. You will receive a report on what each one finds. Save it as a text file on your computer.

At the very top of that page there is a place to place the name of the files that spysweeper keeps noting.
Below are the four files you need to submit, one at a time. The page will scan each file and give you a report on each. Save the reports and post them here. If NOTHING is found on any of them then don't bother to post the report for that one just post back that nothing was found. Here are the files. Do them one at a time.
