The specified service does not exist as an installed service

Hello,

I have a big problem.Yesterday I started my computer and everything worked fine until I wanted to play one game.I double-clicked it and an error showed up saying: "The specified service does not exist as an installed service". I tried some other programs
like CMD(as admin, which worked normally before) and again, it sayd:" C:\Windows\system32\cmd.exe The specified service does not exist as an installed service". So I started to look around web and I found out it could be because trojan or rootkit. I couldn't
turn on windows defender because whenever I tried, it would just open system32. I tried to download
Avast but same error appeared. Then I red about Safe Mode and I tried to start PC in safe mode, but when I would Shift+Restart, Blue screen would show up and there was only "Proceed to Windows" and "Turn off computer" and no
troubleshoot.Can someone tell me what to do because I'm scared that more and more programs would stop working and that I won't be able to use my computer anymore.By the way, none of "Windows" programs work, like regedit, msconfig,cmd(works only as non-admin)

Please help me
