Do you have an antivirus soft? If so, which one. I've seen similar things with other apps. Currently my exe is not signed and it doesn't help. I will have to consider getting a certificate.
Thanks for the info. I'll check that. I had similar issues with a different app that I was working on. Although I can't remember right now if it was Bitdefender or ByteFence. It was different technology, was build on a designated computer. It really gets down to specific parts of the code that are taken for malware.
