I have different Antivirus installed in different PCs!
Automatic "Upgrade" is turned off for all of them!
Yet, Avast decided to upgrade itself without asking, 3 January 2019! (Good Job Avast!)
Since then, I'm having this white\blank screen problem\bug\issue constantly!
Sometimes, when white\blank screen bug occurs, if I right click a file and Choose to "scan with Avast" option, "Windows Explorer" freezes, than "Windows Explorer" and "Avast" restart themselves after some minutes! (Problem seems to be fixed for a certain period of time)!
Rebooting the PC is the only solution to fix the problem!
31 January 2019, and this bug is still not fixed! (Great)

I myself don't recommend people to install Avast anymore!
Avast "Behavior Shield" is a pain in the ass! (I turned it off! It slows down pc, and blocks ".exe" files without even asking or notify!)
Avast "CyberCapture" is another pain in the ass! (I Turned it off too! Even when "Upload file to Avast Lab for deep analysis" option is unchecked, Avast keeps sending files to their servers!)
When I plug a "4 TB" Hdd, Avast freezes Windows OS (The Hdd needs to be unplugged in order to unfreeze windows os)
Believe me Avast, You are going in the wrong way!
Thanks!
