In the manual steps if you delete the files first, the default open command will not work anymore and you've sorta bricked your computer. (google can't run exe files to fix that)

Another wonderful thing about this virus, if you try and search for how to remove it redirects your searches. Had to get the instructions on this page from my phone.

Kdn.exe, mine was avj.exe it's three random letter, in the current version

Also if you're still on xp like me, there's no %localappdata%
%userprofile%\local settings\application data
