Malwarebytes program disappears from 2 PC machines

Recommended Posts

Had Malwarebytes free installed on my 2 laptops at home - linked to home wifi network

Discovered malwarebytes program had gone from both machines. Machines running a bit slow.

Then downloaded and installed latest V of Malwarebytes, ran scan, no problems detected.

Ran Bitdefender quick scan, no problems reported.

Anyone like to help me understand how the program vanished from 2 machines?

Thanks for the support tool report file.  I notice the last install on the 22nd with version 3.8.3.   It shows installed as a free trial.

Unfortunately, this report set does not show history of installs prior to the 22nd. Lacking that, one hesitates to guess about any prior MB install.

 

Let me suggest the following adjustments.

BitDefender needs some adjusting so that it treats Malwarebytes as a trusted application.


What follows is a first step to have Windows 10 show all files and folder. Do not let this spook you out.
There is a how-to at Tenforums. Use either option one or two or three
https://www.tenforums.com/tutorials/7078-turn-off-show-all-folders-windows-10-navigation-pane.html

What follows are the adjustments for BitDefender.
⦁    Open the Bitdefender product installed
⦁    Click VIEW FEATURES
⦁    Under ANTIVIRUS, Click Settings
⦁    Click EXCLUSIONS

⦁    Click ADD
⦁    Ensure Both is selected
⦁    Enter C:\Program Files\Malwarebytes into the text field and click Add
⦁    Repeat for C:\ProgramData\Malwarebytes

⦁    Click ADD
⦁    Ensure Both is selected
⦁    Enter C:\Windows\System32\drivers\mbam.sys into the text field and click Add
⦁    Repeat for the following files:
⦁    C:\Windows\System32\drivers\mwac.sys
⦁    C:\Windows\System32\drivers\mbamswissarmy.sys
⦁    C:\Windows\System32\drivers\mbamchameleon.sys
⦁    C:\Windows\System32\drivers\farflt.sys
⦁    C:\Windows\System32\drivers\mbae64.sys
⦁    Click the back arrow
⦁    Under WEB PROTECTION, click Whitelist


⦁    Enter *.mwbsys.com into the text field and click Add
⦁    Click Save
⦁    Click Close to finish

I would suggest a Windows Restart from the Start menu at this point. Wait for system to reload and to settle beck in.

Thank you  for your assistance, Maurice.

I will make the Bitdefender adjustments once the current scan ends - probably another 36 hours :(

Shall let you know how we get on.

Regards
