I noticed a couple days ago that I have a powershell.exe process in my task manager. When I went to msconfig it has a really long command. Here it is.

C:\Windows\system32\WindowsPowerShell\v1.0\powershell.exe -noprofile -windowstyle hidden -executionpolicy bypass iex ([Text.Encoding]::ASCII.Get.String([Convert]::FromBase64string((gp'HKCU:\Software\Classes\SAJELFZIXHQTV').ADUXJH)));
 
This is really weird because just today a random process that I had problems with before showed up (maybe it's not connected with this but just saying) which is a virus and it tried to download an unsecured driver, as Windows says, on my PC. I hope the stuff I said makes any sense and I gave enough info for you. Could anyone tell me something about this powershell process because it starts up on startup and it's always running. Again, I hope I don't sound like an ignorant moron, maybe it's just a normal startup process.
 
Can this be harmful? If yes, how do I get rid of it, and if not, is this process important to Windows so I can just make it stop running on startup?
