I have just upgraded to Capture One version 22 15.3.0 and have received a warning from my Norton 360 that a suspicious activity attempt by Capture One has been blocked. I have attached a screenshot for you to look at.
I have never experienced this issue before when installing Capture One, so looks like something somewhere has changed.
I have a license for Capture One and was made aware of an update via email and ran the full installer.
as test: I ran the Capture One Trial installer. My Norton 360 was silent.
Maybe, if you ran the new Capture One full installer over already installed Capture One.
Maybe, Norton Data Protector blocked the .tmp file created by the new installer rearranging/updating/cleaning up/ the prior Capture One build - (System32\DriverStore\FileRepository). IDK
