Had many BSOD's, uninstalled Avast Free, no more BSOD's

[WhataMack]

Just passing along my recent experience with Avast Free and BSOD's.

I've had Avast installed for several years, without it causing any apparent issues.  But I'd been having BSOD's on my Windows 10 desktop system over the past couple of months, more and more frequently to the point of having up to four per day.  Most of them were shown as being memory management related, and there were other causes as well.  I'd tried everything I could find from researching this; drivers, virtual memory, running MemTest over and over...all the standard troubleshooting approaches.

Then I happened to come across reports of people having BSOD's and finding out that Avast was the culprit.  After reading these reports, at first I turned off all the Avast shields but the problem was still there.  So I completely uninstalled Avast a week ago and haven't had a BSOD since.  I've also seen big performance improvements on loading of large files in different programs.

- Which version/build of Avast Free..?
- OS..? (32/64 Bit..? - which SP/Build..?)
- Other security related software installed..?
- Which AV(s) did you use before Avast..?

Same exact problem here. I have Avast Premium Security. It turned out that for some reason a port scan coming from a different machine on the same LAN network, causes the system to blue screen of death. Every single time, even after the upgrade to the latest version in March. I have uninstalled Avast and I have tried port scanning many times and never had the problem again. Still I have a paid subscription with Avast and I want this issue to be solved, it is ridiculous that a port scan would cause Windows 10 to completely blue screen like that.

Hi,

Could you perhaps remove the firewall component and let us know if the issue persists, please?
Please see https://support.avast.com/article/Add-Remove-Antivirus-components/
Please restart the computer after removing the Firewall component.

Hello,

Removing the firewall component worked. No more BSOD on port scanning, I have just tried it multiple times. Thank you for that.

Is this an issue you are aware of ? Is it going to be fixed in the next update ?

Thank you very much.
