Windows 10: I have an issue with windows powershell kinda transformed into a virus,

Windows powershell transformed into a virus; So everytime I shutdown my computer and re-open it after an hour or 45 minutes i see 4 powershell windows quickly open and closes and it grows insanely big with RAM memory. i can always close it on task manager and it doesn't show up anymore until i restart my pc.I've tried get rid of it.here's what I tried:-Multiple and different anti-virus-Malwarebytes anti-malwaresBoth anti-virus and Malwarebytes doesn't find the least of trace of it since i think it's camouflaged itself into powershell.-Chiyo

PowerShell randomly poping-up in tool bar

Hello,

Just to verify, do you have any scheduled tasks that uses Powershell? Scheduled tasks makes Powershell window appear periodically on your computer, therefore we suggest that you check the Task Scheduler. Here are the steps:

• Click on Start.
• In the search bar, type Task Scheduler and click on
  
  Task Scheduler in the results.
• Under Active Tasks, check for any tasks that use Powershell and the scheduled time.

If the issue still persist, we suggest that you run a Windows Defender scan to see if it will pick up any malware that the first scan missed.

Let us know the outcome.
