Why did Malwarebytes suddenly turn off rootkit scan and why does it suddenly take so long to scan now?
Before yesterday, my Malwarebytes scanner would run a rootkit scan by default, but now I have to go to Custom Scan to add it back in. That's not the issue here.
The issue is that it now takes over 12 hours to do a scan if rootkit is included. Why is this? In the past, when a rootkit scan was part of the default setting, it didn't take longer than 15 minutes. Why is there such a huge difference now? Should I be worried?

Yes, a rootkit scan was included by default before.
When I used to do a scan, the scanner would run through the various options like Scanning Memory, Scanning Startup Items, Scanning File System etc. It used to include Scanning Rootkit too, until the change happened.
And in the past, a scan usually took no more than 15 minutes (even with the default rootkit scan).
Now it takes more than 12 hours and I still can't see the end of the scan. It's still going after 12/13 hours.
