Vmin Pro configuration very slow due to clamscan

Just installed latest Vmin Pro with install.sh. Now i try to configure it, but each time i save a change (Systems Settings -> Feature and Plugins) the system gets very slow with a process "clamscan -" using all the CPU.
Ok i'm not on a very fast machine at the moment, but the GPL version did not show this behaviour and i do not understand why clamscan is running after enabling or just changing if a module is default or not.

Closed (fixed)
