ok, i repeated the powershell and entered the code like you said, but didnt notice anything different. So i have opened these files and also copied them onto a hard drive, i assume they are safe now and no longer infected.
i should probably remove the "show hidden files" now that i do not need it anymore. Is there anything i have to do in the powershell command to return everything to normal?
and i assume i can use my usb as normal now, right?
