Virus for JJsploit V8.15.0

Before the latest 8.15.0 Update for JJsploit I never had any Virus Notifications but ever since it made me download the new 8.15.0 version its been giving me the same warnings for a virus and ive been reading the threads on the community and they all say its fine and its going to happen but why is it just now happening to me when i downloaded the new version?
