My program is getting a false positive from AVG

My p开发者_Python百科rogram is getting a false positive from AVG. Its just our companies branded version of Ultra VNC. Its only this one company that's identifying it as a virus and we've been using the same copy of that program for almost a year. I know its possible to tell this Anti Virus program the VNC client is safe, but I can't do that for all of our clients. I've tried to find a way to contact this company to see if they can do something to prevent this from happening, but I'm not getting anywhere. Has anyone who's experienced this issue with their software, found a solution?

AVG How To Handle Suspicious False Positive Detection

I had a similar problem. I used old well-known virus approach of using WinAPI through GetProcAddress with function name obfuscation. Another approach is using (preferably non-standard) packers, cryptors and advanced copy-protection systems. If that doesn't help you will have to read more advanced virus manuals.
