My Delphi XE2 programs are always detected as containing a virus on Jotti by ClamAV, while other virus scanners do not detect anything:
This is a Possibly Unwanted Applications according to them and you can't report PUAs on their false positive upload form.
Their contacts page shows two possible avenues you can follow: subscribe and post to their ClamAV mailing-list, or file a bug report in Bugzilla.
A strong argument when reporting is that no one else flags your programs.
Did you also try Virustotal?
