There are always wrong messages (false messages) about Virus and Trojans, from Windows Defender or other Anti Virus Software!
A real virus can not be detected, better said only then, if it has spread on many computers.
The protection is only guaranteed to 99,9% And 0,1% are open.
In this case: Accused! and In doubt against the accused!
Before I upload the software I test it Always on VirusTotal with over 50 virus scanners!
You can see the virus scan results on the download page of the program, for example in ... Download of WinScan2PDF!
Even if the protection is not 100% anyway, the protection is very important!
