When opening browsers (firefox at my case), Malwarebytes-Anti-Exploit blocks the browser. This issue is reported in their site, which declares the fix need to come from Comodo:
New Comodo Bug. We found a second new bug in Comodo which may cause conflict with MBAE and result in browsers not being able to open correctly. It seems when MBAE injects after Comodo there is no problem, but if Comodo injects after MBAE then Comodo doesn't handle the chained hooks correctly. A fresh re-install of MBAE might temporarily solve the problem (as it sometimes makes MBAE handle the API hooks after Comodo) but the definite bug fix must come from Comodo.
When opening browsers (firefox at my case), Malwarebytes-Anti-Exploit blocks the browser, whuich indicates a possible conflict with CIS.
Can you reproduce the problem & if so how reliably?:
If you can, exact steps to reproduce. If not, exactly what you did & what happened:
1:turn on MAE
2:Open firefox browser
3:Firefox is blocked by MAE
One or two sentences explaining what actually happened:
Firefox did not open and MAE showed a notification about blocking an exploit, via its “application hardening Anti heapsprey Enforcment layer”.
One or two sentences explaining what you expected to happen:
For Firefox to open as usual
If a software compatibility problem have you tried the advice to make programs work with CIS?:
Disabling all of Comodo’s components does not fix the problem. I tried to use other Firefox installation (the Tor browser) which didn’t run when MAE was turned on but did not make MAE show a notification. I added browsers to the exclusions of “detect shellcode injections” in HIPS settings and it didn’t help. I have secure shopping and it was disabled.
Any software except CIS/OS involved? If so - name, & exact version:
Malwarebytes-Anti-Exploit v1.09.1.1362 (standalone).
Firefox 52.0.2 (32-bit).
Any other information, eg your guess at the cause, how you tried to fix it etc:
Could be an Issue with MAE alone, or a conflict with Comodo. There are compatibility problems according to Malwarebytes forum: Known Issues & Conflicts - Updated April 16, 2020 - Anti-Exploit Beta - Malwarebytes Forums
