Exploit Protection Affects Roboform in Chrome

Recommended Posts

I could not get my Roboform extension to work properly - the main issue was the option for showing the lower toolbar did not show up in its options. After process of elimination, I can say that  it definitely is the Exploit Protection in MB. When Exploit Protection is off, the Roboform extension in Chrome works fine and all options work. When it is Exploit Protection is on, the Roboform Chrome extension does not work. I tried excluding the whole folder and several files that Roboform support told me could be the problem, but that does not work. Is there something else I can do? Can this be fixed? It must be a pretty new problem, because I did not notice it before today.

I'm not sure where to find a log

You can find Scan and Protection logs within the Malwarebytes 4 program in the following location




RTP stands for Real-Time Protection and is where automatic protection operations would normally be logged




If you click on the View option you should get something similar to the following with other options available.

Weird. There is no log. It is as if MB is blocking something but not considering it log worthy

Please do the following Uninstall and reinstall using the Malwarebytes Support Tool

Please close all browsers and programs before running the tool. Right click and quit MB from the system tray also.

Once done it will attempt to reinstall both Malwarebytes and Privacy VPN.

Please say no and close the X button on the top right for Privacy.

Your computer is showing it needs to be restarted.

Also Bit Defender is known to have conflicts with Malwarebytes.

Also looks like your external is having issues as well.

Also after further review.

In whatever browser you use, turn off ALL other extensions temporally except RoboForm and try again. If it works then you have an extension conflict.

I have already done this on the advice of RF support. No conflicts between extensions. The only thing that causes the problem to go away/return is enabling MB exploit protection for Google Chrome. I'm not sure what you mean by "looks like your external is having issues as well." I did reboot the machine and ran the log gathering tool again (new results attached) to see if there is any difference. I know that MB and Bitdefender have some issues. But I have been using both for years now. And this problem just developed this week, so I wonder if there was a change in the MB exploit definitions?

Very possible. Things do change. I will ask @Arthi to look int this.

OK. Thanks. Let me know if anything comes up.

As for the harddisk, it looks like that is my external  hard drive, which seems to be working fine. Is there something I should check or do with it? It is a WD Passport HD.

Did @Arthi have any insight? RoboForm in Chrome is still not working with exploit protection on. Interestingly, RoboForm in Firefox is working fine, even with exploit protection on.

RoboForm technical support replied to me. This what they said. Does it help solve the problem?


It takes Chrome to start RoboForm's process rf-chrome-nm-host.exe (so named native messaging host) to let RoboForm extension work in co-operation with RoboForm for Desktop that makes the lower toolbar available in Chrome.
The problem is that Chrome does not starts rf-chrome-nm-host.exe directly, it starts cmd.exe first, and the Exploit Protection option makes your security software treat cmd.exe started by the browser as a potential threat.
As the result, RoboForm's process cannot start, either, and adding RoboForm files in your security software white list cannot help as your antimalware does not ban RoboForm's process indeed, it bans cmd.exe.

Unlike Chrome, Firefox does not need cmd.exe, it starts RoboForm's process directly (please don't be confused with 'chrome' in the name of rf-chrome-nm-host.exe, this is intended for all browsers with RoboForm extension including Firefox).
This problem is not a RoboForm issue and cannot be fixed in RoboForm, neither we could explain why it takes to start cmd.exe first to run native messaging host for the browser (this would affect any extension that needs native messaging).
