Malwarebytes Premium Web protection not turning at start up

[cybot]

I have been noticing that lately that recently my copy of MBAM has not been able to turn on web protection at start up. a look at the event viewer shows that mbamtray.exe failed to start with a 0xc000005 error with faulting module Qt5core.dll.

 

I can restart the mbam service to get everything working again, but then an event in the event viewer appears that says "Session "MBAMSwissArmy" failed to start with the following error: 0xC0000035" 

 

I am unable to determine what the second error means, I know the 0xc0000005 is basically a access denied error. but I don't know why mbam is being denied access to it's own files. I have the mbam support tool, and it asked me to restart after hitting the repair button. but I have yet to determine if the issue is fixed yet.

Hello and Welcome!

I see your running ESET Security... its possible that there is a conflict between ESET and MB3, you may want to exclude the Malwarebytes in your ESET.

Click here for the full exclusion list (Malwarebytes for Windows antivirus exclusions list)

Adding exclusions in ESET

[cybot]

ok thanks. I will try that.

[cybot]

umm... the link you gave was for v4.0 of eset AV, I am using Eset Smart Security Premium 12. so the options are different.

 

I have an option to exclude processes, and an option to exclude files and directories. which one should I choose?

I would start with Processes, but you may have to do both

problem seems to have been solved. but the events in the event viewer seem to be a separate issue. I updated my copy of MBAM on my surface pro, and as soon as it updated, the error I noted above, the 0xc000005 and the 0xC0000035 errors started showing up on that device too. It would appear that the mbamtray/qt5core.dll  and the mbamswissarmy errors are in the current version MBAM. the errors appear to be nonfatal, so everything should be alright.

 

My PC is Windows 7 Ultimate SP1 x64

the Surface Pro is running (of course) Windows 10 Pro (1809)

 

looking around the forum, others are seeing this error as well

tried to go back to thelast version of mbam (3.3.1) that was on the surface  since it did not cause any errors,  but as soon as it started to update the definitions, the exploit protection turned off and the event viewer said the anti exploit service could not start because it was not a valid win32 application. I don't know if this is because of an error in the update files, or because I was using an old version of mbam.

[Firefox]

Your certainly welcome to install v3.3.1 however there has been many improvements and fixed done since that version that is why we recommend you stay on the latest version.

between now and when I last posted, I performed a reset operation on the surface pro. I did choose to keep personal files, but all installed apps got removed. there weren't very many apps to begin with installed, so it wasn't a problem. when I went to reinstall mbam (latest version), I thought I would have to go and track down my license info, but much to my surprise, mbam was already activated with my license info. when I looked at the event viewer, there were still messages about mbam, but they were only informational, no errors, or warnings about mbam were present. If this is the solution to those 0xc00000005 and 0xc00000035 errors, this poses a problem for me and many other windows 7 OEM users, as normally we don't have the OS installation files for doing a repair or even a clean install. in my case, my only options seems to be do a factory restore, or upgrade to windows 8 Pro or windows 10 Pro (I have valid licenses for both). for now I will use what repair options I have available to see if I can get anywhere, mainly chkdsk, sfc, and dism.

If something like this happens again it shouldn't be necessary to reinstall Windows or anything else that drastic.  A clean install of Malwarebytes itself should correct it.  The following instructions may be used if you come across this issue again (and of course for anyone else reading this topic who may have similar issues):

1. Download and run the Malwarebytes Support Tool
2. Accept the EULA and click Advanced tab on the left (not Start Repair)
3. Click the Clean button, and allow it to restart your system and then reinstall Malwarebytes, either by allowing the tool to do so when it offers to on restart, or by downloading and installing the latest version from here
   

Also, with regards to Windows, you should be able to get a copy of the installation media from here and I'd recommend reading the FAQ located here.  If you are unable to download the installation media that way, I'd suggest contacting the system vendor/manufacturer as they should provide you with installation media (assuming your system does not have a Windows recovery partition already on the drive of your system).
