I’m running Webroot SecureAnywhere EndPoint Protection v188.8.131.52
I’ve been battling a strange issue where my whole OS becomes unresponsive. I get the “(Unresponsive)” message on all windows. Sometimes the screen goes black with only a mouse cursor movable. When it begins, the start menu stops working and I can’t start new applications. Task manager won’t open and CTRL+ALT+DEL doesn’t do anything. Any applications that were running before have a random chance to continue working or freeze. I can’t reboot. If I am able to issue the reboot command it never happens, likely because Windows can’t close all the hung windows.
I thought it might be a hardware issue, maybe a failing HDD but I’ve ran numerous tests. All the tests tell me that nothing is wrong. I have been keeping Task Manager open all the time just to see what is going on. I’ve finally noticed a pattern. Webroot kicks up to 10% CPU usage when the event begins. After that, Webroot remains steady at 10% usage and everything else slows down to a crawl until power cycle. I can easily reproduce the problem by running Visual Studio 2019, it will cause this behavior every time. I can open VS2019 and then close it, but Webroot takes over. So VS2019 is not even running while the problem is happening.
I left it running for hours. It never recovers. Webroot remains at 10% until I shut the computer off.
