After Malwarebytes new update, Pc works strange and Firefox unable to open


Recommended Posts

Hi, I have Malwarebytes Pro versión 4.0.4. I shutted down my computer last night after various days Malwarebytes kept asking me to restart to update it (I rarely shut down, I mainly suspend it). My PC worked fine as always, till today. 

After restarting, now not only my Firefox and Vivaldi browsers doesn't open, my antivirus Kaspersky doesnt start either and the Pc runs slow. At first I was really ansious of a virus messing with my pc and somehow affecting my antivirus, browsers and Malwarebytes. Then I remembered the only thing I did on my pc between yesterday and today, was restarting to update malwarebytes. I tried killing Kaspersky and Malwarebytes process on the task manager, but its imposible, I tried with cmd but I dont know how to locate them.

So, fancy new interface, but I almost piss myself with the new behavior of my pc. The only browser that works now is Microsoft Edge. 

How to revert to the last versión of malwarebytes to see if it resolves the issue?

Hi,

Sorry to see the troubles described.  That has to do with the pc having  Kaspersky Free Version: 20.0.14.1085

If you were to uninstall Kasperky & reboot, you would see things go back to normal, such as Firefox not seeming to open  ( it gets started but hangs  & one can see it on Task Manager).

I saw the same behaviors on my rig when I tested Kaspersky Total Security 2020    Version: 20.0.14.1085

There is a definite issues with Kaspersky.   ( which you do not need.  This pc has Widows 10 with Windows Defender  ( which is a fully capable & powerful AV )

Your pc will do just fine with Malwarebytes for Windows Premium &  Windows Defender.

.

See the notes from LiquidTension

There are three different known workarounds:

  1. Method 1: Uninstall the Kaspersky product.
  2. Method 2: Exclude affected applications within Malwarebytes.
  3. Method 3: Disable Ransomware Protection in Malwarebytes.

Keep us advised.Just to be more frank, the Windows Defender antivirus that comes with Windows 10 is very very capable & powerful.  And it is Free with Windows 10  and Windows  8.1.

You do not need Kaspersky on your pc.   You will do well with just Malwarebytes for Windows Premium & the Windows Defender.

Sincerely.
