As you may know there is a lovely new ransomware out there spreading and i would like to share some info on how to prevent it from running if you get infected, running these in powershell will create 3 empty files that would get created by the ransomware upon completion of its intended purpose so by having them already in the proper folder it should stop it from activating you can run these commands in powershell as an administrator to make those 3 files: New-Item c:\windows\perfc -type file New-Item c:\windows\perfc.dll -type file New-Item c:\windows\perfc.dat -type file Set-ItemProperty c:\windows\perfc -name IsReadOnly -value $true Set-ItemProperty c:\windows\perfc.dll -name IsReadOnly -value $true Set-ItemProperty c:\windows\perfc.dat -name IsReadOnly -value $true Again this won't prevent infection but it should stop the ransomware from activating since it will search for these files 1st on the computer. Please take this precautionary measure for the sake of your PCs.
