Bob -
I can't be sure how legitimate that exe is. Take a look at this page also at the same site:
http://www.2-spyware.com/file-autoclk-exe.html The description is of a helpful exe for some people. Yet, other information on this page says it is related to spyware. It seems that almost anyone can log-in to this site and add or otherwise modify information. I could be wrong about that since I did not actually log-in.
I know very little about this site. At the bottom of that page, I clicked on a link for ESolutions (owner/operator/maintainer) and got this page:
http://www.esolutions.lt/ The above link is to a page of links that appears to be legitimate but who really knows.

Most of the links are not related to the same subject of computer security.
Anyway, since it is listed as a utility and not an actual Windows program, it is probably safe to get rid of it. I got to this info by using Google. Many of the page results came up in foreign languages to me. I only know english. Perhaps some others here can check out some of the other Google results for autoclk.exe?
