After updating Avast Free using its built-in updater, I restarted my computer. Then I got blue screen. My computer can’t start at all. I tried to uninstall it using Windows 10 Safe Mode but it said got no log. I managed to uninstall using Avast Clear and my computer can restart.
After more than two years of testing both Avast Free and Avast Basic, I give up. I uninstalled Avast and installed another antivirus which didn’t give me any problems at all.
From my observations these last two years, some of the Shields don’t work well:
Web Shield - it seems that the developers don’t really test the blacklisted sites. They blacklist if someone complain about it and then wait for someone to fill out their form to whitelist.
Ransomware Shield - doesn’t work well on folders in external drives. Only works if the external drives are plugged in after Avast starts and not if they are plugged in on PC start.
Scan Centre: no way to clear Scan History easily.
Software Updater: now have to buy Premium to stop auto-updates.
And now BSOD when updating Avast.
So my final goodbye to Avast and a thank you to all those who responded to my posts in previous and this Forum.
