[ RESOLVED ] Extremely fast scan, then extremely slow

[EndangeredPootisBird]

As shown in the attached pictures, an scan with Malwarebytes instantly skips to 120k, sometimes to 200k files, scanned when beginning to scan File System, then it becomes extremely slow despite using 100% of my CPU, I have ensured its not some conflict between my main antivirus by adding the Malwarebytes folder to the exclusions

   • 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.
   •  Repair System: Includes various system-related repairs in case a Windows service is not functioning correctly that Malwarebytes for Windows is dependent on. It is not recommended to use any Repair System options unless instructed by a Malwarebytes Support agent.
   • Anonymously help the community by providing usage and threat statistics: Unchecking this option will prevent Malwarebytes Support Tool from sending anonymous telemetry data on usage of the program.

@EndangeredPootisBird

Please turn off the following settings if they are on. They re not needed during scanning and slows down the scan tremendously.

That is extremely weird, now it finished in 1 minute, 22 seconds. I have seen a large amount of people facing problems with having it on, yet I have never experienced any problems with having Expert system algorithms on, no false positives and no scan slowdowns, experimental technology is experimental for a reason I suppose.

It is the rootkit scan that slows it down the most.

The rootkit scan was the cause, no need for anything else.
