I recently did a clean wipe of my HDD using diskpart…clean all and did a clean install of Win10 Pro x64, which starts at Version1709, build 16299.125. The reason for this is because a new Windows update would not install, and I couldn’t figure out the conflict. Now I realize that unfortunately it is Comodo that causes a BSOD - Unexpected Kernel Mode Trap.
I reinstalled the OS, then tried installing all Windows updates first (build 16299.248), and that worked fine, and then Avira installed without problems as well, but when I installed the latest free version of Comodo today, I still get the BSOD mentioned above. There’s something about it that does not allow Win10 to boot after the required Comodo restart.
Win10 does load in Safe Mode, and I’d read about uninstalling Comodo Security Essentials, so I tried that, using both the CSE uninstaller in Control Panel - Programs and Features, as well as using Revo Uninstaller Forced Uninstall. Unfortunately, even with only the Comodo Firewall, I still got the BSOD. Then I tried uninstalling everything Comodo related using once again Comodo’s uninstaller and Revo, and once again BSOD, unless I’m in Safe Mode. The ONLY thing that works is a system restore.
I don’t understand the conflict - every other computer and laptop in the home has the same Win 10 Pro (latest version and build), Avira free AV, Comodo free firewall, and there are no problems. I cleaned the inside of my computer, did a MemTest 86 which went through 9 passes with no errors, checked the HDD using chkdsk /r in elevated command prompt - no issues, and the power supply is ok, too.
I’m completely stumped as to why Comodo is so troublesome on this one computer. So I have to live without it on this one machine, but would really rather not have to. I’m back to using Windows Defender Firewall, hoping it’ll suffice until there’s a solution to this Comodo conundrum. Thanks.
