Hello,
I've been using MC now for a long time. I inscribed myself to the BETA channel. Now since updating to v7.1 (build 2344) MC was quarantined twice with the reason "unauthorized file encryption" while copying files. I went back to the latest non-beta version and since then the virus scanner is OK again with MC.
I'm working under Windows 7 Professional, Service Pack 1.
Regards,
Matthias
