Investigating
We are investigating an issue where WithSecure Device Control may block executables from running when using an external disc, as well as some virtual discs. The issue started after the installation of the following updates: Capricorn: 2022-08-22_06; Hydra: 2022-08-22_02 and F-Secure Ultralight Core (64-bit) 2022-08-22_01
A workaround is available: disable Device Control for the duration of the incident. Note that disabling Device Control will reduce your overall security.
