In seriousness, I’d recommend going to BleepingComputer or one of the other malware expert sites for this.
If you want to stay here, here’s what we do.
Copy this into Notepad, then save it as ‘fix.reg’ (have ‘all files’ selected so that you don’t end up with fix.reg.txt’).
Windows Registry Editor Version 5.00
[-HKEY_CLASSES_ROOT\.exe]
[-HKEY_CURRENT_USER\Software\Classes\.exe]
[-HKEY_CURRENT_USER\Software\Classes\secfile]
[HKEY_CLASSES_ROOT\.exe]
@=”exefile”
“Content Type”=”application/x-msdownload”
[HKEY_CLASSES_ROOT\exefile\shell\open\command]
@=”\”%1\” %*”
Download rkill and run it. A clean PC and a USB key would help.
Download MalwareBytes, install, update, run.
See where we are from there.
