The fix that worked for us was to go to Start - Control Panel - Programs and Features, then uninstall Malwarebytes Version 3.X.X.... then restart the computer (note "Malwarebytes Endpoint Agent" was still installed). After restarting the computer, the software reinstalled on it's own (possibly because Malwarebytes Endpoint Agent was still installed) and the computer was back to normal. Before the fix, we tried updating the database, turning off web protection, etc but that did not work and the memory/RAM was about full; causing the computer to be very slow, even while uninstalling the software.

Got it. Thanks for the info! Just to confirm, is the only product we need to install on user computers for protection just the 32/64-bit Endpoint Agent Installer?

We currently have Endpoint Security and are trialing Endpoint Protection. With Endpoint Security, users are able to launch Malwarebytes from their Start menus and run their own scans. I don't see this option with Endpoint Protection. I downloaded the 64-bit Endpoint Agent Installer Only and it shows the computer on the cloud, but doesn't show a Start menu option to load Malwarebytes and run my own scans. Is this a feature available with Endpoint Protection? Do I need to download more than just the 64-bit Endpoint Agent Installer or does that give me the Anti-Malware software, Anti-Exploit software, etc? I tried downloading the Malwarebytes 3.0 from the list of downloads, however, it asked me for a premium license code. Any help is appreciated. Thanks.

We are using Symantec Endpoint Cloud.

Due to the news of the massive ransomware attack today, I changed all computers to move to the policy above. I'm no longer testing the startup delay as I want to make sure computers have live protection.

Another update: On a computer with live MBAM protection enabled (website blocking ENABLED and no delay set) I had issues this morning. I noticed it when i was unable to run an installer for a .exe file, then I opened File Explorer and had the "green bar bug". A full Symantec scan was ran the day before. I looked at the task manager (Ctrl + Shift + Esc) and saw that MBAMservice.exe was still running. I tried the command prompt, mbamapi /protection -stop , but after hitting enter it got stuck and didn't go through. I tried restarting and it got stuck as expected so I did a hard reboot. I started up the computer, File Explorer was working again. I opened command prompt, ran the command mbamapi /protection -stop and that worked correctly.

It's pretty much a fresh copy of Windows 10 (Creator's Update) on a VMware virtual machine. When I installed Malwarebytes, the installer asked to download .Net 3.5 so I did that during the installation and it's enabled in the Windows Features. @djacobson I appreciate your help and time spent to look at this issue for us.

I loaded a clean Windows 10 64-bit virtual machine that has Windows 10 and VMware tools installed on it (no Symantec or additional 3rd party software). I then installed Malwarebytes and restarted the computer. After that I opened Task Manager, stopped MBAMservice.exe and it still locked up. We do not use Kaseya.

@kieferschild I appreciate the updates. If I open task manager and stop MBAMservice.exe it locks up my computer as you mentioned. If i stop it via CMD it does not happen. I've created another policy that has website blocking disabled and has a 90 second delay, and added a couple computers to it for testing.

@djacobson Will this topic continue to be updated after converting it to a case? I'm still having the same issues as Kieferschild and am at the point that I'm removing the live MBAM protection like Kieferschild has done on several computers, in order for the computers to work correctly.

Adding mbamservice.exe to the exclusion list didn't help as one of the affected computers had issues this morning. Another user reached out today and said they were having the green bar loading bug in File Explorer, resulting in another hard shutdown to fix the issue.

I tried turning off the Website Blocking on a computer while it was having the issues but the issues remained. I went into Task Manager and tried force closing mbamservice.exe, but that made the issues much worse and froze up the computer. I’ll try adding mbamservice.exe to my list of exclusions within Symantec. Also to answer a question you asked earlier: On an affected computer and a non-affected computer, msmpeng.exe was not listed within Task Manager under the Details tab.

kieferschild - Users have local administrator rights on the computers that are having issues. I'll be curious to see if adding those two folders to your exclusion list helps. djacobson - Computers with and without user logon scripts are both having issues. Do you want me to try disabling the web blocker on Symantec after the computer is affected or before? I prefer to keep the web blocker on and try to disable it after the computer has the issue. djacobson - Should I try adding mbamservice.exe to our list of exclusions within our SEP policy?

Several of our users are experiencing the same issues. Users first notice it when they go into File Explorer to access their network drives, then see a green bar loading at the top of the window and no drives show up. If they try to use a program such as command prompt, the program won't load; and when users try to restart their computers, it gets stuck in the restart screen with a spinning circle. Several users are experiencing this and have to force shut down their computers to fix the issue. I was able to target the issue down to Malwarebytes by uninstalling the Malwarebytes software on one of our Windows 10 computers and leaving it on another (both were having the issues above). The computer without Malwarebytes stopped having the issues while the other continued to have the issues. I just recently reinstalled the software after the Windows 10 Creator's update, but the computer started having issues again the next day. We use Symantec Endpoint Protection along with our Malwarebytes Endpoint Protection (Malwarebytes Anti-Malware + Malwarebytes Anti-Exploit for Business)
