Extra scan has been added to my schedule.

Recommended Posts

I have a scheduled scan that runs every day at 07:45 and is also set to scan for Root Kits. An extra scan has been added to my schedule for some reason. It's similar to what I would see if I had done a fresh install of MWB with a time of 02:23 and "scan for root kits" off.  It seems to have started on the 5th. January.  This happened previously but I just deleted the unwanted one.  Now it has happened again. Looking at the reports there doesn't seem to have been an update applied as the product is still at :: 1.0.508.  This is only happening on this PC (Win 10 Pro 1809, Version 1809  17763.253.  Another PC on Win10 Pro and a Laptop on Win 10 Home don't seem to have the problem but aren't used as much as this one. Date/Time in U.K. format.

The only thing I can think that might cause this would be if the software was being reset to default settings or if it was having some kind of issues with its configuration files/data files and falling back on the backup files containing the default settings.

It may be useful to get a set of logs showing the details of your installation to see what might be happening:

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

If the extra scan is still scheduled then please get a set before as well as after removing it.

Thanks for your response.   I thought that the logs might be required so I had already run the Support Tool and attached the file to my original post. It is under the screenshot. Only thing is, I can't remember if I had deleted the "extra scan" before running the tool!!  I think it is with the extra scan still present.

Great, thanks.  Yep, I missed it under the images.

I just checked and the logs don't show the extra scheduled scan, just the one you created that starts at 7:45 so I'm guessing it was created after deleting it.  That's OK as I did find this in one of the logs from the program:

01/04/19 " 07:37:06.332" 31109 0dd0 113c INFO ScanControllerImpl mb::scancontrollerimpl::ScanScheduler::UpdateScheduledScans "scanscheduler.cpp" 1091 "License state changed from Free to Licensed and there are no scheduled scans. Adding a default daily scan."

I also found this:

01/08/19 " 07:45:00.000" 159781 0fcc 1de4 INFO ScanControllerImpl mb::scancontrollerimpl::ScanControllerImpl::StartScheduledScanNotification "scancontrollerimplhelper.cpp" 466 "Another scan is in progress, cannot start the scheduled scan at this time."

It looks like something may have gotten messed up with the license/configuration files similar to what I mentioned as a possibility in my first reply above, so I'm thinking that's what's causing it.  As for how to address it, I suspect the new build that was just released might correct it as they mention this in the changelogs, so it may be that the software is losing its registration, reverts to free mode, finds it again, returns to Premium, then adds the default scheduled scan back because at the time it fails to see the existing scheduled scan you had already created:

This new package addresses improvements to functionality for certain licensing operations.

Please download and install the latest version from here over the top of your existing version then restart if prompted to complete the installation process and keep an eye on things and let us know if the issue returns, but hopefully that will fix it.

Problem returned. Has been running o.k. since updating as advised. Problem seems to have started yesterday afternoon. I had been out and put my PC on when I returned to download a Word doc. that I needed.  Ran the Support Tool and gathered the logs. Removed the "extra scan" and gathered the logs again.  Results attached.

Hi RTL434,

Thanks for the updated logs.

Do you occasionally disable/change your network adapter or disconnect from the Internet for extended periods of time?

Please do the following:

  • Ensure Malwarebytes Premium is activated.
  • Download MBSupportInfo.exe using the following link:
  • Double-click MBSupportInfo.exe to run the tool.
  • Note: If you are prompted by Windows SmartScreen, click More Info followed by Run anyway.
  • A Command Prompt window will briefly appear then close.
  • A file named SupportInfo.dat will be created in the same folder as MBSupportInfo.exe.
  • Please rename this file to SupportInfo-Before.dat and move it to a safe location.
  • Please wait until the next time the issue occurs.
  • Afterwards, please rerun the MBSupportInfo.exe tool.
  • A new file named SupportInfo.dat will be created. Please rename this file to SupportInfo-After.dat.
  • Please attach both files to a forum post.

I normally power this PC up in the morning around 07:30 and use it for about 2 hours. It is then powered down. This is the PC that I use most of the time, and is hard-wired to the Router. I have occasionally disabled the adapter.  I also have another Desktop and a Laptop with Premium installed. Both use  Wi-fi adapters, although I use a USB3>LAN connection on a Thursday when I backup the Laptop to my NAS. They haven't exhibited the problem. The Laptop I would use in the evening if I was in need of a computer, whilst the other Desktop is rarely used--but kept updated. When not in use they are fully powered down.

Have downloaded and run the tool and saved the file.  Will await the next instance and then run it again.

Thanks for your response.

Well it has happened again.  I had been looking at the Forum and had seen that an updated Component Package 586 had been released. I clicked on Install Application Updates and it updated o.k.  Now the extra scan is there. Ran the tool as requested and attaching the files. Originally I was on version 3.6.1 and had captured the file. I reran it when I went to 3.7.1. Am attaching both these before files along with the after one created today.  Haven't deleted the extra scan yet. Installed the update on my laptop  Windows 10 Home and no problem there.

Thanks for the file.

We have a defect filed for this issue. It's occurring because the license state of your product is changing and the "Recover missed tasks" setting in your scheduled scan is not set to default. As a result, the program erroneously believes that no scheduled scan is configured and creates a new one. This will fixed in a future update.

Thanks for the response. That does seem to be the problem. I have just checked the other Desktop and the laptop and they have it set. Don't have it set on this PC as it is the one I use daily and is usually powered on by the time of the scheduled scan--the others might be off for days. Anyway I can live with that and thanks again for your time.
