Hi, I am a software developer, still working with Powerbuilder 6.5.1. Approx. 1 month ago, NIS 2012 started deleting my software - the reason apparently is SONAR. Up to approx mid. march 2012 everything was ok for years. The software is virus and malware free. Interestingly, it is removed by NIS2012 on Windows XP Home with SP3 only. It stays on Windows XP Professional and Windows 7 - the very same up to date NIS 2012 sees no problem. I know my users can restore file and exclude it from scanning, it works, but the problem is that the whole situation is weird and creates an impression that we introduce a security threat. Application runs fine until a keyboard key is pressed. SONAR as a reason for deleting EXE says something about intercepting a pressed key. We can't digitally sign Powerbuilder EXE because it won't run after signing. What other options do we have?
