Still doing it for me too... also for months...
I did everything posted here: uninstalling, cleaning, repairing, stopping firewall, checking for virus, checking for malware, whatsoever... still doing it. Very very annoying.
Here my config:
- Win 8.1
- x64
- avast antivirus pgm ver. 12.3.2280 (build 12.3.3154.19) (last available)
- signatures 161024-1
- zone alarm firewall 14.1.057.000 (just in case it matters)
I also confirm that there is a strange coincidence with Thunderbird email software: sometimes, not always, I would say one out 2, I get a Thunderbird warning message about confirming a security exception at the same time as Avast agents get down. I have however no idea about which one comes first (my Thunderbird check emails only every 10 minutes).
I am seriously considering changing Avast for an other antivirus software, even though I am with them since the 90's... You can't trust a security software which stops when ever it wishes to.
