Hello!
Yes, it is an old war with various antivirus software. Avast and DrWeb marked the program as PUP (potentially unwanted program) because of using toolbar offers during installation. But at the moment and in this version of distributive there are no any tollbar installers, ads, or any other software, only the original program. We had a conversation with these antiviruses representatives and explained, that we are no longer use bundled installers, but these marks are still remain. Have no ideas what Suspicious.Cloud mark was placed for. I think that other users, who installed our program successfully, can prove that the program doesn’t create any suspicious activity.
