Hello everyone. First Post here for me. Not going to hound or whine for a fix, just looking for a way to deal with this drag on my PC's performance issue. So some details that others might provide are missing here. I've read a lot of posts on this issue, and it seems to be at least a year since a MB Representative said on this Forum that a fix was "in the works". Obviously MB is not interested in fixing this issue or they CAN'T fix it. Either way, if I can't find a workaround to at least deal with it, it will be time for me to find another scanner. 

I used to leave my PC turned on 24/7 & just locked the screen when finished for the day. Things like system wide malware scans were never a problem as I just scheduled them when I knew I would be away, usually late at night. I no longer leave the PC on. Problem now is that as soon as I turn it on for the day, Malware Bytes (among others) jump immediately into action and gobble up huge portions of my PC’s resources, causing very noticeable and bothersome lags in performance for the things I want to use the PC for. This in spite of a 4.0 GHz, 6-Core CPU, 16GB of RAM and a SSD System drive. A task as simple as just loading a program can take as long as 2-3 minutes where it normally takes only 7-10 SECONDS!

My question is this:  Is there a FIX for this? If not, is there a way to setup MB to either limit its use of resources (preferred) OR, if that is not possible, set MB to turn off the PC after I *MANUALLY* initiate a scan?

Appreciate whatever help anyone can provide,


MB Premium Version:       
Component package version:    1.0.262
Update package version:            1.0.4306

Now it

Greetings :)

Please try installing the latest release to see if it fixes the issue for you.  You may do so by opening Malwarebytes and going to Settings>Application and clicking on the Install Application Updates button and following the prompts to install the latest version.

Once that's complete and you've restarted the system if required to complete the installation process, see if the issue is now fixed.

Please let us know how it goes, and if it doesn't work, go ahead and post the diagnostic logs requested in the above automated reply under the section where it says technical issues.

exile360: Thanks so much for such a prompt reply!

I *could* do the "latest release" thing, and normally I would have already done it by now. But the reason I haven't so far is a deliberate hold-back due to the high number of performance complaint posts I have read on this forum. It would seem from reading those that people who upgraded to 3.4 are experiencing the problem even worse than I am. So given their experiences, do you *really* think this might fix my very similar problem??? Please tell me why i should just toss aside those 'warnings' and forge ahead to 3.4? Is there a 3.4 Build that supersedes the versions in those posts that fixes this problem? Has MB announced that the problem has been fixed? Inquiring minds want to know. 

Thanks again,

Yes, there is at least one known issue with the performance of 3.4.4 under some circumstances, however it also contains a very large number of fixes for other bugs and issues in previous versions, including several performance issues related to version 3.3.1 so I would still recommend giving it a try.  If it doesn't help you can always uninstall and roll back to a previous version (we can provide a download link for the older version if required).

Thanks! That's the kind of detail I was looking for. I will give it a try. 

Tell me something however:  I have 3.3.1 installed, but when I right-click on the TaskBar Icon and select 'Check for Updates', MB does not advise me of any Updates.  It doesn't do ANYTHING - just tells me "Awesome! You're protected.'" What's up with that?

Thanks again,

The option to check for updates from the tray just checks for database updates, not program version updates so that's why it's saying that.  To check for application updates you have to open Malwarebytes and go to Settings>Application and click the Install Application Updates button.
