I assume you're referring to threats listed in the Threat window, right? What I was talking about were active threats reported in ERA.
The threat records in the threat logs can be muted (marked as resolved) manually once you have taken care of the threat. Once muted, they will turn from red to black & white:

Please elaborate more on what doesn't work for you. We will consider resolving found threats automatically if running a full disk scan doesn't yield any active threats.
I will test it the next time, actually no active threads (and yes i mean active threads and not the other "counter" and the Client was cleaned by eras)
It could be, a bug of the old Version (i update the Server and the Test Clients after this appears the first time)
