total security core scanner getss stuck in donation site

I am using total security in a couple of sites and never had any problems. Today, after I upgraded to 4.2.1 in two sites the core scanner doesn’t stop and has to be aborted after 20 minutes or so … What is going on. Are there errors in my WP installations or can we expect an upgrade of total secutity?

Greetings, Adil
