beta exe version triggers anti virus and now stable version wont activate

[Frances Proctor]

so was playing around with the beta version and it crashed went to open it again and got a notification of a new version available and decided to try the exe format.

when I try to install it my av software blocks it saying it contains a threat  GenVariantFragtor.206121 so I went to open the stable version and it wants me to activate it  which i did do before as i have used it for a while now.  anyway filled in my info and it now says wait a moment and try again which never goes away and if I close it and try again i still get the same thing. 

I am going to close everything down and restart my computer see if that changes anything

Edit: after restart exe versions of stable 2.04 apps working fine designer 2 beta exe (latest build) still triggers av software (Bit Defender)  after temporarily disabling bit defender beta exe installs fine

This is a false positive notification; and Bitdefender unfortunately reports such notifications frequently. A very reliable alternative is Microsoft's Defender; moreover, it does not tear additional security holes in the system.
