Anyone else had strange issues with MBSetup-278628F2.exe ?


Recommended Posts

This update nearly trashed my Win10 (up to date 21H2) desktop , went into a restart loop that was difficult to stop. Did so eventually , but then MB would not start , so uninstalled , ran clean , tried a manual install , after a new D/L , same issue , looping restarts. Use the Recovery Tool to try a fix ,  no dice , then manually uninstalled MB , restarted to a stable system , ran sfc /scannow , fixed a few minor files , restarted , tried to install MB , got the msg "Mb will not install on this PC " . Given it was all fine prior to this update , and no significant process's were running at the time.

I did have a similar issue like this last year , on a diff PC , and needed support for a fix , seems the D/L for that Ver had a fault. I'm hoping that's not the case now.

I guess one of the issues I dislike is that MB does not popup signal when it's about to update , unless U have the console window up , would be very helpful if it flagged with a box requesting permission to do so , as U may be in a critical process that could well interfere with a smooth install process.

Hello @freds and :welcome::

Although it may be best to move your topic to the Windows Malware Removal Help & Support subforum, a good start can be made here.

The official/highest integrity MBSetup.exe is like a small so-called setup stub and has not changed since the first week of this month. Even then, it likely was updated for enhancements, whereas last Wednesday's much larger mb4_offline installer is made available with each new official release of Malwarebytes for Windows.

So while you are waiting for an expert/staffer to reply, please download/run/reply with the results from the Malwarebytes Support Tool's grab for analysis:

  1. Download the Malwarebytes Support Tool.
  2. In your Downloads folder, open the mb-support-x.x.x.xxx.exe file.
  3. In the User Account Control pop-up window, click Yes to continue the installation.
  4. Run the MBST Support Tool.
  5. In the left navigation pane of the Malwarebytes Support Tool GUI, click Advanced.
  6. In the Advanced Options, click Gather Logs. A status diagram displays the tool is Getting logs from your machine.
  7. Soon a zip file named mbst-grab-results.zip will be saved to your desktop, please upload that file in your next reply here.

Thank you.

Thanks for your reply. I did run the tool at the time of the error , as soon as the system was stable. Strangely , it did not produce the required log file and nor did it clean the MB install , as a couple of files were left. I have just re d/l'd the tool and run it , it did not find an MB install ( I did uninstall manually) and did produce a log file.

This computer has some services that are not loading and could use some general cleanup work.

Windows 10 is not without antivirus. It has Windows Defender antivirus built-in and it is on par with Avast antivirus.

I would recommend you uninstall Avast and then we'll look at uninstalling a couple other apps and do some clean up to correct these errors. Then when done if you want to install Malwarebytes we will, or if you don't want to then we'll just leave it at that and not install it.

Yes , I'm aware of Win10's AV , it was active until I installed MB , and now it appears to not be able to be restarted. Avast was simply a backstop measure. Cleanup has completed and Win reports all is ok. I have reinstalled MB from the standalone pkg , and all appears well , will continue to monitor this desktop.

Thanks for your suggestions

Okay, thanks for the update. If you don't enable Malwarebytes to register to the Security Center in Settings then Malwarebytes and Windows Defender should both run alongside each other with no issues.

 

Here are some information to help keep the computer clean.

 

Let's go ahead and do some clean-up work and remove the tools and logs we've run.

Please download KpRm by kernel-panik and save it to your desktop.

  • right-click kprm_(version).exe and select Run as Administrator.
  • Read and accept the disclaimer.
  • When the tool opens, ensure all boxes under Actions are checked.
  • Under Delete Quarantines select Delete Now, then click Run.
  • Once complete, click OK.
  • A log will open in Notepad titled kprm-(date).txt.
  • Please attach that file to your next reply. (not compulsory)

Thanks for the suggestions. Yes , quite a few services on this PC are "off" a symptom of working for the "Lovely" people at Alphabet , where many services are required to be "off" if one is using Win10. I'm aware of some issues this causes , but was contractually obliged to make the changes , been too lazy to turn them back since retiring.

I do use robust passwords for most PC's that have I/Net access , generally use 12~16 Chrs , and as above , had to have robust rotating strategies.

This last event has highlighted some flaws , but as my wife and I are Flood refugees at the moment , & I do not have my "Normal" network access with all it's attendant security , I'm just "Winging" it for the next few months.

I do rely heavily on MB to provide the majority of my protection , and have done for years , but I have found a few issues with updates that seem to be a little MS like , and sometimes cause bigger issues than they are trying to fix. I usually don't take any update from MS until it's been out there for some time and been more rigorously tested , I'd been a "Beta" tester for years , got annoyed that some updates were plainly still at that stage, and released generally.

Thanks again , have a great day !
