I read at a forum last night that the security application Antiy Ghostbusters (all versions) report your installer as having:
--> Backdoor.CCInvader.20.
You may find more information on this application at:

 A trial verion, with full features, may be downloaded at this link

 As your site states firmly that you have no "backdoors" or other such features, I thought it in your best interests to deal with this issue quickly. As this story is likely to spread very quickly on the web.
I myself performed such a test on a current download of your application and found the same result.
