Shortly after upgrading to build 723, I upgraded Windows 10 to the Fall Creators Update, plus there was an update to Comodo Internet Security. I then started to get a bunch of random BSOD's. I used the utility WhoCrashed to give me some visibility into the mini dumps and it kept saying it was related to ntoskrnl.exe, which can point to RAM issues. I ran the Windows Memory Diagnostic and it did not find and issues with my RAM. So, I assumed that one of these three updates was not playing well together. I had been planning to do a clean install of Windows 10 FCU anyways (the upgrade was a test run to look for issues), so I proceeded to do so. However, I wanted to slowly ease back into HMP.A and Comodo to see if any BSOD's crop up. I installed Windows on November 29th. I installed HMP.A on December 1st. I have not see any BSOD's up to today. However, I did find some interesting information in the Comodo Forums found here (see below in green), but I haven't reinstalled Comodo yet so I can't confirm. I'm wondering if any other members of this forum have tested this combination?

After uninstalling it I installed Comodo Antivirus 10 again and rebooted as part of the installation process. No BSOD this time! I was triggered by a message from umesh that development found hmpalert.sys to be a possible trigger for the issue (I sent in dumps and logs), which I recognized as being part of HitmanPro Alert. I'm now running Comodo Antivirus 10.0.2.6420 with the lastest database. http://forums.comodo.com/Smileys/default/smiley.gif If you're running HitmanPro Alert also, you might want to try to disable/remove it to see if your issues are solved also. Thanks umesh and others at Comodo!
