Mapwarebytes slowed my computer way down

[Tom77]

I'm new to Malwarebytes. It's been running okay the last few days but today my computer Win10 started running extremely slow. I shut MB down and my computer was back up to speed. Tried to start MB again and received a message "couldn't connect to the service". Is there anyway to fix the issue?

   • Clean: Performs an automated uninstallation of all Malwarebytes products installed to the computer and prompts to install the latest version of Malwarebytes for Windows afterwards. The Premium license key is backed up and reinstated. All user configurations and other data are removed. This process requires a reboot.

Can you please collect and upload as an attachment the diagnostic data using our MBST?

• Download and run the Malwarebytes Support Tool
• Accept the EULA and click Advanced tab on the left (not Start Repair)
• Click the Gather Logs button, and once it completes, attach the zip file it creates on your desktop to your next reply

I downloaded the tool and ran repair. My computer is up to speed and MB is running fine now. 

[Tom77]

MB is doing it's daily scan, has been scanning for over an hour and still running. Should I cancel the scan and run the MB Support tool?

Restart the computer and this time get me the log as requested on Christmas, DO NOT try any repair yourself.

Here's the zip file.

First,

I  highly suggest turning off fast startup in Windows. Then restart.

Next, You need to adjust the scan scheduled time to a time of day where the computer is on and you are not needing it.

Personally I have not run a scheduled scan in a long time. I do them manually once a week and do not do any thing else until the scan is over.

How long does a manual standard threat scan take on your computer?

[Tom77]

I turned off fast start up and rebooted. The manual threat scan took 41+ minutes.

That seems a little long. Were you using the computer for anything else during the scan?

Your log shows rootkit scanning on. It is not needed and slows the scan down. I would turn it off.

[Tom77]

So I don't need to scan for rootkits? I had my browser open during the scan. My whole system is running slowly.

Not on any regular basis. Just when you think you are having an infection issue.

During a manual scan, Malwarebytes uses 100% of your resources. It is best to not use the computer at all during a scan.

Do another scan without rootkit scanning enabled and no programs or browsers open and see how long it takes.

[Tom77]

The scan took 6+ minutes without rootkits.

That is more like it.🙂

Did you decide and change the time for the scheduled scans?

[Tom77]

Yes, and changed scheduled scans to once per week. 

[Porthos]

Sounds good. If you have anymore issues were here for you. Be safe

[Tom77]

Thanks!
