Malwarebytes Premium affecting any Mozilla programs

Recommended Posts

Immediately after activating Malwarebytes Premium, my Win 10 system blocked Firefox, Thunderbird, and any files associated with them.  I ran all scans with no results. Reinstalled Windows and all programs. Everything was fine until I re-activated Malwarebytes free to Premium again.......same result - Firefox and Thunderbird will not open, and freeze when trying to uninstall; and computer slows down.

I even did a complete registry purge of any Mozilla products, and installed an older version of Firefox afterwards......same result. With Malwarebytes Premium de-activated, everything goes back to normal, and runs fast again.

Does anyone have any workarounds so I can still run Premium?

Do you have Kaspersky also installed?

Yes,
I do.

That is the issue. The latest version of Kaspersky is known to have problems with Malwarebytes.

I suggest going back to version of Kaspersky till the issues are fully resolved. Less hassle than making a bunch of exclusions to get them to work together.

Hi @SA63   

It is very important that you advise us which specific Kaspersky product +  the version number + if it has the latest patch  ( like G )  !

It is important that we know if this has Kaspersky Total Security or Kaspersky Internet Security  ( + version).

The link cited above is a good way for plunking in Trusted applications + Exclusions in each of Kaspersky and Malwarebytes 4.

There is I believe 1 or 2 folder-name differences between Total  Security and Internet Security.

 

The exclusions are the starter basics. The mutual exclusions are always a good idea.     I would caution you it will not be totally nirvana after this.

By the way, the version number of Mozilla Firefox does not matter.  I would advise that you go forward and get the newest security release of Firefox.

 

p.s.  To have Kaspersky show you the full version installed,  start the Kaspersky program.  Click the "support figure icon" at the bottom.

You should see a screen with full detail.

Thank you.

I have Kaspersky Total Security.  Version number: 20.0.14.1085 (g).

Also running the latest versions of both Firefox and Thunderbird.

The problems do not exist when only the free version of Malwarebytes is installed and running........only when it is upgraded to Premium version.

Can you please advise any workarounds, or have I wasted money on a Malwarebytes upgrade that will not work happily with my preferred security program?

Start with the mutual trust exclusions outlined in the thread, starting with this post  & then all that follow it

https://forums.malwarebytes.com/topic/255397-malwarebytes-ver-40449/?do=findComment&comment=1355698

 

Since you have Kaspersky Total Security, you will need to substitute the Kaspersky Total Security folder instead of  "Kaspersky Internet Security 20.0"

 

Putting trust exclusions as listed in all the sections there is a good practice.

If after that, you run into issue on Firefox or Thunderbird,  then you ought to place exclusions for Firefox , Thunderbird in the Allow list of Malwarebytes 4

You may just list the folder where the program is installed.   You would elect for a folder exception in the Allow list.

For example,  C:\Program Files (x86)\Mozilla Firefox    for Firefox

See Malwarebytes version 4 steps: https://support.malwarebytes.com/docs/DOC-3543

 

.

If after all this you still encounter some issue,  Please see this link  for one of 3 possible alternate work-arounds.

And another is to uninstall Kaspersky Total Security 20  and then install Kaspersky Total Security version 19.   Version 19 works fine with Malwarebytes.

This is a link at Kaspersky for Kaspersky Total Security  version 19 installer.

Thank you,

If I go with Kaspersky version 19 instead of 20, does that mean I need to be locked in to version 19 forever,  and if so, how do I stop it automatically upgrading itself?

No,  It does not have to be forever.

The way to manage the Kaspersky (future ) upgrade is this:

Start Kaspersky.   Click Settings icon.

Click on "Additional"  from the list.

Click "Update".

Tick  ( select / click ) the 2nd line which is "Do not download new version automatically and do not notify me when they are available"

Apply the adjustment.   Close the window.

Then continue to monitor this sub-forum as well as the Kaspersky Support forum for potential new future versions.

We have investigated this issue and believe we have a fix that addresses the root cause. The fix is now available in the latest version of the standalone Malwarebytes Anti-Ransomware Beta. 

We plan to make this available for Malwarebytes version 4 in an upcoming release. An announcement will be made on the forum once an update for this issue is released. 

Thank you for your continued feedback and understanding.

 

As always, you should monitor the top pinned posts at the top of this sub-forum for future new releases of Malwarebytes 4

Hi,

This should be of interest to all who have both Kaspersky 2020  and Malwarebytes 4 Premium

There is a new Malwarebytes Beta 4.1.0.56 version 1.0.853 component package update that addresses a few issues.  Those include

Quote

Certain Ransomware protection incompatibilities with Kaspersky, iTunes and Photoshop

See the announcement here https://forums.malwarebytes.com/topic/257042-malwarebytes-41-beta/?do=findComment&comment=1367093

 

If your Malwarebytes 4 program is already enabled to Beta option, a number of you will be prompted to get the update.

If your pc does not have 1.0.853 component package update, and are in the Beta, you can just go to the General tab and do a "Check for updates"

 

If you need to turn on the Beta option, go to Settings >> General tab, scroll down to Beta Updates and enable it.

 

If you elect to not get the beta, monitor the top pinned notes for future announcement of release

https://forums.malwarebytes.com/forum/41-malwarebytes-for-windows-support-forum/

 

You can easily check the details of your MB4 installation by going to Settings >  About tab

NOTE:  IF you currently have the standalone Malwarebytes Anti-Ransomware Beta, you will want to uninstall that first & do a Windows Restart & then get the BETA  MB4.

Malwarebytes Components Update: 4.1.0.56 version 1.0.854 addresses Certain Ransomware protection incompatibilities with Kaspersky

This release includes, along with other things, the fix for Kaspersky, iTunes and Photoshop

If your PC is already on Version 4  ( regular or beta) you will be updated to it automatically as long as automatic updates are enabled. If you have temporarily disabled them then please enable them to allow this update.

 

The original Kaspersky conflict issue was due to a change made by Kaspersky on their Antivirus 20.0.14.1085(patch E) programs. As their change was causing issues for our users we took it upon ourselves to work on developing a workaround for this conflict.

Kaspersky Anti-Virus 20 version 20.0.14.1085 was released on July 24, 2019
Patch E for Kaspersky Anti-Virus version 20.0.14.1085 was released on October 23, 2019 which is when the issue was first reported to us.
Patch I for Kaspersky Anti-Virus version 20.0.14.1085 was released on February 18, 2020 and is the latest at the time of this posting on 2020-03-19

 

Please note that although our update works around this issue, at any time in the future another update from Kaspersky could once again potentially create another conflict. This applies to most other security software as well since we do not have control over what other security program changes other vendors make. On Windows 10 the built-in Microsoft Windows Defender has consistently worked pretty well alongside Malwarebytes when enabled for quite a while now for those that have chosen to use it.
