Very slow application launches

[PLE]

I've been using Malwarebytes for years without problems. This past Saturday (4 days ago), on my home server, applications began to launch excruciatingly slow. Even something as simple as Powershell, which normally launches virtually instantaneously, now takes over a minute. Other programs can take several minutes, including Malwarebytes itself. Turning off Realtime Malware Protection restored  everything to normal. I've tried uninstalling and reinstalling, but the problem returns several minutes after booting the computer. Additionally, Malware scans now hang during the update check. Last night's scan ran for over six hours, stuck on checking updates, before I terminated it this morning.

I've attached the files generated by the support tool.

 

I'm wondering if the program updated in my absence on Saturday. If so, would it be possible to roll back to the previous version while this is sorted out?

Greetings,

Please do the following to see if it corrects the issue:

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 how it goes and if the issue still persists.

Thanks

Hi, Thanks for responding.

I've used the support tool several times to clean the system and reinstall. Each time, the system starts normally, but after several minutes, anywhere from 1 to about 15 or 20, the system once again exhibits the problem I've been having: slow application launches. Additionally the Malwarebytes scanner hangs.

For the time being, I've uninstalled version 4 and reinstalled version 3, which has now been running for several hours without trouble. I also have three other computers running version 4 without trouble.

Also even though it works for some the consumer/Home version is not designed for nor supported on any Server OS.
