malwarebytes prevents google chrome from opening


Recommended Posts

Hello community, 

i'm facing a weird issue with google chrome.

After updating my malwarebytes to version 3.5.1.2522 (component package version: 1.0.374 and update package version: 1.0.5468), i can't open my google chrome.

Malwarebytes anti-exploit keeps on blocking google chrome from opening.

I uninstalled and reinstalled google chrome, removed all the extensions, deleted profiles, installed Google chrome canary but nothing seems to be working.

I also contacted google chrome support forum and followed everything they suggested but nothing works.

Could someone help me in fixing this annoying problem please? 

all other browsers work absolutely fine.

below is the report i extracted from malwarebytes when it blocks chrome from opening.

regards,

Amil

It looks like you've bumped up your Exploit Protection options, which can trigger issues like this. I'd recommend resetting these to defaults by going to Settings -> Protection -> Advanced Settings and clicking "Reset to Defaults". Click Apply and then try to open Chrome again.

Just FYI, I'm running Windows 7 x64 and I'm using a Chromium based browser (SRWare Iron Portable Edition, latest build) and I have all of the Advanced Settings in Malwarebytes Exploit Protection component enabled (except Memory Patch Hijack Protection for MS Office which won't stay enabled (you have to exit Malwarebytes completely then launch it again to realize it's not being enabled as the checkbox remains checked/enabled in the UI otherwise when you try to enable it even though it's actually not activating; this was due to a compatibility bug found in recent Malwarebytes 3 builds and this was the solution the Developers chose to implement for the time being until the issue is resolved and the setting may be safely enabled again) and I haven't had any problems running Iron.  I did however have Exploit Protection block Firefox Portable immediately after installing the latest build of Firefox recently and then launching it, but that only occurred the first time I attempted launching it and the issue hasn't returned since so I'm guessing one of the telemetry or other initial/first launch routines executed by Firefox triggered the detection/block by Malwarebytes.

I did have Chrome installed previously but don't have much use for it any more since all plugins and functions that work in Chrome also work in Iron (just without Google's ads and constant monitoring/tracking/telemetry etc.) so I removed it for the time being.  I might reinstall Chrome to test this issue and see if I can replicate it, and if so, I'll gather the pertinent data for the Devs and will report it to the team.
