Opening Task Manager Slows PC to Crawl - Windows 10 Pro 1709

Hello-

I had this issue and I couldn't find anywhere with a working solution.

Finally after trying every which thing I could think of, I learned that disabling powershell in the programs and features solves the issue.

That is, if you hit the windows key and then type in "programs", "Add or remove programs" should be an option.  Click on it.  Then on this screen choose "Programs and features" on the right.  From here choose "turn windows features on or off" and then scroll all the way to the bottom of the new window that pops up and uncheck both powershell boxes.

This still allows you to use powershell too!

Unfortunately I just paid for a year of Webroot and I am the entire IT dept, I don't have the budget nor the time to swap this out right now.

Seems like no matter what I switch to for anti-virus there's always problems on the horizon.

I am so glad I found this post. I ran into this issue only today and it was driving me crazy. I noticed this post was from Dec. 2017 and it is now March 2018 and I am having the same problem so It has apparently not been fixed by Webroot.

I contacted Webroot support to find the best possible workaround.

I will say that allowing Chrome in their identity protection setting only partially fixed the issue for me. So I think Webroot is doing more scanning of other apps and it's still causing problems with Task Manager. I haven't had time yet to test things further unfortunately.

I am quite disappointed because I just recently switched our company to Webroot from something else that I was having a lot of issues with. 

Our IT dept uninstalled Webroot and installed a different anti-virus. This fixed it.

I'm having this same exact issue. Contacting Webroot support today. I'd say I'm switching to Malwarebytes but their recent update brought down 100's of my nodes during production hours. Looks like we are running out of good AV choices.
