I use Neobook Rapid Application Builder from neosoftware.com. This morning it ran smoothly, but this evening (local time) I'm getting this error when trying to access/start the program:

Previously other users of Neobook has received this or similar messages from Pest Patrol or Norton AV, but I don't use neither of those. I use Avast (freeware version), and I can suspect this is causing the error message.
Can it be a false positive of something Avast sees as malware?
Please make sure neobook.exe is not on your LP5 list, if any.
