Thanks a lot for your quick reply!
I have 2 folders: "14111301" and "14111301_stream", and 1 file: "aswdefs.ini" configuration settings file, which contains the same date:
[Definitions]
Latest=14111301
So, does it mean that avast has the files to perform an update? But it won't auto-update...
Just to be clear, if I check the settings I can see that "A new version of the program [2015.10.0.2208] is available!", and I can update manually - but I want it to occur automatically.
