Slow (22 seconds) to open powershell

[TheThing]

Hi there.

I was wondering if somebody could help me diagnose the insane long time it takes for powershell to open up. When I open powershell, I get the powershell message but it doesn't give me the command line prompt until exactly 22 seconds later every time:
 

Windows PowerShell

Try the new cross-platform PowerShell https://aka.ms/pscore6

Wait 22 seconds

Windows PowerShell

Try the new cross-platform PowerShell https://aka.ms/pscore6

PS C:\Users\My Name Here> _

This also happened with Windows Defender but I noticed with Windows defender, if I disabled realtime protection, powershell would open instantly. I thought maybe Kaspersky would have better realtime protection (I'm a developer so I use powershell a lot) but it seems Kaspersky is also taking forever to scan this.

Is there a way for me to whitelist this or at least see which files it is scanning so that I can maybe clean it up or something? Maybe modules or scripts?

Thanks in advance.

Hello @TheThing, 

Welcome!

We get a response in less than a second... 

1. Which KAV version & patch(x), x = letter, is installed, on the Windows taskbar, or hidden icons, rightclick the Kaspersky icon, select About? 
2. Which Windows OS version & build -> in Windows Search, type Info ? 
3. Has PowerShell response time always been poor, if "no", when did the issue start? 

Please let us know? 

Thank you?

1) 21.3.10.391 (h)
2) 10.0.19044 Build 19044
3) Definitely not, it started a few days or a week past and I think I was doing some changes to it or installing some compopnents or something? I don't exactly remember.

I thought it was something to do with my installation, however after googling it, I found a solution on Super User stackoverflow: https://superuser.com/a/1411591

When I tried an alternative to the suggested solution of disabling realtime protection in windows defender, it worked flawlessly. Disabling realtime protection changed the startup time to less than a second. After installing Kaspersky and even trying disabling all protection for a minute using Kaspersky's "Pause protection", the startup time did become lower as the title indicates, it still takes a long time to open powershell even with Kaspersky's protection being paused for a whole minute.

Is defender maybe still running in the background or something?

Please try this : CMD > MSCONFIG 

1) Disable WD in the Services

2) Disable WD at StartUp

3) Reboot

Hmm, I checked and windows defender is not running after all so I don't think that would change anything ?

Can you please restore Kaspersky default settings and then disable separately the protection modules ?
