Hello mxh and welcome.

 

Can you please tell me at what point had the Anti-Malware program been "abending"?   Was it as soon as it opened, or did you have to do something on the Dashboard screen?

 

It looks like at this point you removed the Anti-Malware program?   How did you go about doing that?

 

There appears to be a trace leftover of version 1.75, which needs removing.

Tell me, did you have version 1.75 before ?

or did you have an earlier version of 2.0 ?

 

FYI, the "appcrash" condition can be overcome rather easily if only you would not have jumped ahead to uninstall the program.

As we go along, let us guide you to what needs to be done and I would ask that you don't do any changes / fixes / addition on your own.

 

This pc appears to have Bitdefender A-V, so tell me, does it also include a firewall component or some sort of web filter of its own?

Also, what version / release of BitDefender is this?

Bitdefender works well with our program.   IIRC, it needs to be the latest release.

Thanks for the quick reply.

 

Malwarebytes stops working whenever I click update or scan. Otherwise I can use the program without any problems.

 

I used mbam-clean-2.0.2.0.exe to remove Malwarebytes. Then reinstalled Malwarebytes. This was done a few times. Also used the mbam-chamelon-3.1.4.0 to install Malwarebytes once.

 

I don't recall installing version 1.75. However, I went through past posts from others in this forum and may have followed instructions to install v.1.75 from old links.

 

The bitdefender only has virus shield and auto scan. It's version 1.0.21.1099.

 

I specifically allowed malwarebytes through my firewall.

If there is a later "appcrash" I need for you to just stop and tell me the details.   And then I will guide you about the fix.

 

For now, you need to run the older version of 1.75-clean utility first.

 

Preparation:

Close ( if any) open work documents and save your work files ( if any opened).

Close opened programs so that you have a clear view on the Desktop.

 

Make a mental note:  This is on Windows 7 thus for  most all the tools and the setup-install EXE that need to be run you need to do a RIGHT-Click on the EXE and select Run as Administrator and allow to run.  Reply YES when prompted by User Account Control ( Windows).

That is one key ingredient.

 

Save the attached zip file.  Desktop is the easiest typically.

Then unzip content.

Then run the EXE tool.

 

When done with that, then you can use the clean install procedure listed here.

 

You may run that other "mbam-clean" as well, your choice.   That would be fine.

 

Once that is done, and the new version 2.0.2.1012 is in place, let me know.

 

I would suggest making these settings ( assuming you have a paid license).

Take a look inside the program. Start the Anti-Malware. Click on the Settings icon at the top bar up at top.
Then click the **Advanced Settings** button at the left.
Be sure all top 3 lines on that window are check-marked ( selected ).

Now a couple of changes for each of the Update task & the Threat scan task in the Scheduler.
Click on **Automated Scheduling** button.

Locate and click once on **Check for Updates** line and press Edit. Then press the Advanced button at bottom left.
Slide the window up so you can see all of it. {press the mouse on the very top bar and slide UP }
A few changes are needed.
Look at the "starting time" of the task and use some good time when you know that your computer will be on & powered & that Windows would be on at that time.
Look at the line in Schedule Options. UN-check "Show notification after successful update".

In the Frequency and Settings. Select Hourly and I suggest using the Recurrence at 4 hours.
In the Recovery Options put a check-mark on "Recover missed tasks" and select 1 hour
When done, press the OK button.

Locate and click once on the Threat Scan line and press Edit.Then press the Advanced button at bottom left.
Slide the window up so you can see all of it. {press the mouse on the very top bar and slide UP }

In the Schedule Options, put a check-mark on the line Terminate program when no threats are found
{when no malwares are detected you want the scheduled task to close}.

In the Frequency and Settings block.
You should have Daily and the recurrence set to 1 day.
now UN-check the line Check for updates before scanning {{that line should be always off otherwise the task may not run at the time set. It maybe run +/- 15 minutes of that period.}

In the Recovery Options put a check-mark on "Recover missed tasks" and select 1 hour
When done, press the OK button.

When completely done, close the window.

A fresh Windows start would be good to do at this point. Use Logoff and Restart Windows.

Malwarebytes Anti-Malware works well and should run alongside antivirus software without conflicts. In some rare instances, exclusions may need to be set for your specific antivirus product to achieve the best possible system performance.
I suggest putting in trust settings in your antivirus, as follows:
Please "put as Trusted" (i.e., put Trust settings) for the following MBAM exe files within your Antivirus Software whitelist :

Note: If using a software firewall besides the built in "Windows Firewall" you'll need to exclude them from it as well

For 32-bit Windows Vista or Windows 7 or Windows XP:

C:\Program Files\Malwarebytes Anti-Malware\mbam.exe
C:\Program Files\Malwarebytes Anti-Malware\mbamdor.exe
C:\Program Files\Malwarebytes Anti-Malware\mbampt.exe
C:\Program Files\Malwarebytes Anti-Malware\mbamservice.exe
C:\Program Files\Malwarebytes Anti-Malware\mbamscheduler.exe

For 64 bit versions of Windows Vista or Windows 7 or Windows 8:

C:\Program Files (x86)\Malwarebytes Anti-Malware\mbam.exe
C:\Program Files (x86)\Malwarebytes Anti-Malware\mbamdor.exe
C:\Program Files (x86)\Malwarebytes Anti-Malware\mbampt.exe
C:\Program Files (x86)\Malwarebytes Anti-Malware\mbamservice.exe
C:\Program Files (x86)\Malwarebytes Anti-Malware\mbamscheduler.exe

Note: If using a software firewall besides the built in Windows Firewall you'll need to exclude MBAM.EXE and MBAMSERVICE.EXE from it as well

Note: Once that's done, please make sure that if either of those programs has any sort of web filter, that you add the following as a trusted site:
data-cdn.mbamupdates.com

Check your Anti-Virus/Internet-Security application to see if you can add exclusions for specific applications/files to ignore.
You may need to contact their technical support or check their support website for instructions.
You will need to set your Anti-Virus/Internet-Security to ignore/exclude the files I listed above.

Hi,

 

I tried the suggestions above and Malwarebytes still give me the same error.

Tried to run Malwarebytes scan or update without the Bitdefender and Firewall and still had the same error.

Turned UAC completely off too.

 

I found the below thread. Followed instructions to replace my net.conf file and the problem was solved.

Thank you for all the help!!!!!!!!  :)
