False positive for virus on LexFloatServer.exe

We use CryptLex for the licensing of our APIS products. Part of the solution is a floating license service installed together with our software on a server in the clients network. Some antivirus scanners will create a false positive for this service, LexFloatServer.exe. CryptLex have gone through a hardening process for this service, and we can confirm that it is safe and free of virus. Attached is a "Declaration of Software Security" from CryptLex.
