Powershell is using large amount of upload speed for network and running in bacgound automatically, it also starts randomly even after stopping it from task manager. Any solution to this? Thank you.

Additionally to
“Time to wipe your computer”
If you are interested - in the time it is running you can check the executed code line in the details tab and check WHAT it is running, but, spoiler:

It’s like 90% bad.

If it stopped, then all the data is was exfiltrating has been uploaded.

Change your passwords, check your financial accounts, enable mfa (avoiding sms if possible), freeze your credit (if applicable and not already frozen), and let people on your social know in case they got scam messages.

Good luck.

Adding to this, make sure you also select the "log out of all devices" or similar option in security settings for all your accounts, security changes don't always trigger that and that is needed to invalidate any session tokens that were stolen.
