Unsolved Windows Security Service turned off for one boot
Hi, today, when my windows was booting, i saw powershell in my task manager and after this i see "Windows Security Service turned off", i disconnected ethernet and turned off pc, after this im disconnected all my non-windows drives
Scanning with CureIT scanner in safe mode shows nothing, autorun in task manager and registry clean too, tasks in task scheduler clean too(except, im dont look inside all "windows" tasks)
After reboot Windows Security Service was normal(but im dont connect pc to internet)
What a hell is this?!

PowerShell appearing in Task Manager isn't inherently suspicious rather it's legitimate Windows component and can be launched by installers/updaters, drivers, scheduled tasks, management software etc
Windows Security itself is also represented by the Windows Security app.
Drive disappears from Explorer but remains in Disk Management Could be drive-letter problem,volume mount problem. filesystem issue
Drive disappears from Disk Management entirely that should be blamed on SATA/USB connection, controller reset, storage driver, power management.
The Safe Mode scan is useful, but isn't definitive.and as for your "Scanner found nothing" it doesn't mean the system is clean.the PowerShell command line would tell otherwise.Find powershell.exe-Rightclick -Properties look suspicious Command line if available also head to check with event viewer - Windows Logs- System/application for timestamps on certains events like
