I had previously disabled MBAM real-time.
Am presently using PrevX. (and PrivateFirewall 7.0.20.36)
I also disabled AVAST 5.0.0.396 (free) file agent. (the only agent I had installed anyway)
Installed build 415 on top and rebooted.
When I right-clicked on the AVAST tray icon and chose to reenable the file agent, it froze...
Mouse was moving, but evertything else was frozen, PC irresponsive.
I'm presently uploading the memory dump, named "FBlais.7z" this time.
Upon reboot, AVAST is running so far...
