TTActivator v.1.22 issue

Greetings to everyone, I've been a member for a few weeks and thanks to the helpful posts on here successfully updated several devices to the current navcores and maps.
This morning I was going to load a different map onto an XL satnav and started TTActivator as normal (v.1.20) and received a pop up saying that an update was available and did I wish to update, I selected yes and the update downloaded, however, trying to run this update sent the anti-virus into overdrive (Windows 11, 64bit Windows Defender anti-virus), is this a 'false positive' I can add as an exception, or is there something suspicious happening?
Regards,

Steve
