How to stop automatic scan at startup with Free version?


Recommended Posts

Not that long ago, maybe a month or two ago, I had to reinstall both MBM and my main Antivirus software. Because of the reinstall, I was giving a free trial of MBM. Now ever since my trial has run out, I'll notice every once in awhile that my computer will get really laggy at start up, to the point where it actually freezes and stutters from time to time, because MBM decided to scan at start up and I didn't realize it because I'm never notified. It's really annoying, and I'd really would like to stop it so that I can just use it for manual scanning purposes. Is there any way to stop it? I'm afraid I'm going to be doing something really CPU-heavy one day when it starts scanning and I won't realize it until the system has crashed or I lose what I had been working on.

The free version does not do any scans automatically. Please post the logs from the "Bot" reply above and someone will take a look.

Greetings,

Please open Malwarebytes and go to Settings>Scan Schedule and click on the item listed there to highlight it then click Delete.  Once that's done, restart your system and verify that it is no longer executing a scan on system start.

Please let us know if the issue is now resolved or not.

Thanks

I'm not seeing anything under the scan schedule page.

If there's no scheduled scan then Malwarebytes shouldn't be running an automatic scan on startup.  I'm not sure what's causing this to occur, but it may help to take a look at your startup entries as that may give us a clue:

Create an Autoruns Log:

Please download Sysinternals Autoruns from here and save it to your desktop.

Note: If using Windows VistaWindows 7Windows 8/8.1 or Windows 10 then you also need to do the following:

Right-click on Autoruns.exe and select Properties
Click on the Compatibility tab
Under Privilege Level check the box next to Run this program as an administrator
Click on Apply then click OK

  • Double-click Autoruns.exe to run it.
  • Once it starts, please press the Esc key on your keyboard.
  • Now that scanning is stopped, click on the Options button at the top of the program and verify that the following are checked, if they are unchecked, check them:

Hide empty locations
Hide Windows entries

  • Click on the Options button at the top of the program and select Scan Options... then in the Autoruns Scan Options dialog enable/check the following two options:

Verify code signatures
Check VirusTotal.com

  • Once that's done click the Rescan button at the bottom of the Autoruns Scan Options dialog and this will start the scan again, this time let it finish.
  • When it's finished and says Ready. on the lower left of the program window, please click on the File button at the top of the program and select Save and save the file to your desktop and close Autoruns.
  • Right click on the file on your desktop that you just saved and hover your mouse over Send To and select Compressed (zipped) Folder
  • Attach the ZIP folder you just created to your next reply

It's odd, I don't see anything showing that Malwarebytes should be launching a scan on boot, so maybe it's some kind of strange corruption/issue with its configuration files causing it.  To attempt to fix it, please do the following:

  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 Clean button, and allow it to restart your system and then reinstall Malwarebytes, either by allowing the tool to do so when it offers to on restart, or by downloading and installing the latest version from here

Please let us know if that resolved the issue or not.

By the way, I also noticed you have a lot of unnecessary startup items that launch every time your computer boots.  While that wouldn't cause this issue, it could definitely slow your system down and reduce its performance.  Once we're done here, if you would like assistance in cleaning up some of the unneeded startups then you may create a new topic in our general PC help area requesting assistance with it and posting your Autoruns log that you created above by clicking here.  I also noticed that you have Java installed.  If you don't use it/need it for anything then I would definitely recommend removing it as it is known to be a frequent target for malicious exploits and to have lots of vulnerabilities that pose a risk to your system's security.  If you wish to remove it you may run the Java uninstall tool found here.

Thank you for the help! I don't know if it has worked quite yet as I just reinstalled using these steps, but I'll give it a few days and come back with a final update on the topic. That said the uninstall/clean and reinstall went smoothly, so I am hopeful.

I'll also make sure to take your advice on the startup items. I disabled a few before but I never know what is necessary and unnecessary, so I'll definitely be asking.
