Malwarebytes Antimalware hangs (registered version)

[TNHarleyRider]

Let me say first of all that I have used the free download of this program on at least a couple of occasions and was very impressed. So much so that I decided to purchase the full version of the program so that I could have the real time protection.

Sadly, the program now hangs up the PC after as much as a few minutes to a couple of hours. This happens even if the program is doing a scan meaning that the only thing Malwarebytes Antimalware is doing is the background protection. The PC is locked up to the point where I cannot Ctrl+Alt+Delete to bring up the Task Manager to terminate the service. I am unable to do an orderly shut down or restart. The only option at this point is a hard power down. In all other respects this Windows Vista system is stable and reliable. Without using this software I can leave the PC on for days at a time without any software issues.

Needless to say, I am not happy to have spent the $25 for real time protection only to find that the real time protection hangs up the PC.

Correction to the above:

This happens even if the program is not doing a scan meaning that the only thing Malwarebytes Antimalware is doing is the background protection.

Hello TNHarleyRider,

Please follow coconutnut's directions listed above.

Let me know how this goes for your system. Thank you!

I tried excluding the files listed above, but it didn't do any good. After rebooting via the power switch I would see the problem described in the following links:

Logon process has failed to create the security options dialog

Logon process has failed to create...

The only time I have seen the behavior described in the links above was after having protection turned on in Malwarebytes Antimalware.

I have removed Malware Bytes Antimalware from my PC.

Hello TNHarleyRider,

If you'd be so kind, I'd like to get to the bottom of the issue please let me take a look at a process monitor log from you.

Create a Process Monitor Log:

• Create a new folder on your desktop called Logs
  
• Please download Process Monitor from here and save it to your desktop
  
• Double-click on Procmon.exe to run it
  
• In Process Monitor, click on File at the top and select Backing Files...
  
• Click the circle to the left of Use file named: and click the ... button
  
• Browse to the Logs folder you just created and type MBAM Log in the File name: box and click Save
  
• Exit Process Monitor and open it again so that it starts creating the logs
  
• Re-create the issue
  
• Close Process Monitor
  
• Right-click on the Logs folder on your desktop and hover your mouse over Send To and select Compressed (zipped) Folder
  
• Please attach the Logs.zip file you just created to your next reply
  

Thank you!
