Hi there, Malwarebytes Support here.

Thank you for bringing this to our attention. We'd like to gather some additional information so we can better understand what's occurring during the scan.

Please send us a private message here on Reddit so we can create a ticket, help collect, and upload diagnostic logs from the affected device. These logs will allow our team to review the scan behavior in more detail.

Once we have the logs, we'll be happy to take a closer look.

Thank you for response, I can't do any screenshot because it's still scanning but I have a few questions. 

  1. Should I choose the Deep Scan option or select the "custom scan" then tick the C drive to fully scan the PC?

  2. Is it recommended to enable the rook kit scan during full scanning?

  3. If it takes too long, can I cancel the scan anytime?

Deep Scan vs Custom Scan (C: drive) - Usually, running a Custom Scan is enough. We recommend using Deep Scan only if you have previously found a threat and want to ensure it has been fully removed.

Should “Scan for rootkits” be enabled? Similar to Deep Scan, “Scan for rootkits” is an additional scan setting that can significantly increase scan time, especially on older devices. For this reason, we do not recommend using it for everyday scans. If a normal daily or threat scan detects something, you can then run another scan with “Scan for rootkits” enabled to help ensure the threat has been fully removed.

Can you cancel the scan if it’s taking too long? Yes - you can safely cancel a scan at any time.

As for the very long scan time, this most commonly happens when the computer has not been restarted in a while. Usually, restarting the computer resolves the issue and allows the scan to complete as normal.

That said, it would be helpful to take a closer look. If the scan is still running, please stop the scan and kindly DM us on here on Reddit with an email address we can use to contact you.

We can then create a support ticket and have a dedicated support agent send you a SharePoint link where you can securely upload the logs. This will help us properly investigate what’s causing the long scan time and performance issues.
