Yeah, we all know that the sticky is supposed to be read. I did. Everyone also know that moderation action will be taken against people who don't follow that sticky. I know that too.
However, I thought it would be important and helpful to list to people a way to keep the scan.dll file from coming back. On my computer at least, every time I delete it, WoW tries to reinstall the file. So, to combat that, you can do this easy thing, which will make it so that Blizzard doesn't reinstall the scan.dll file.
Delete both scan.dll and scan.dll.new from your World of Warcraft folder. From here on, be hasty, as we don't want to have it come back. Next, go to notepad. Save your blank file in the World of Warcraft folder and name it "Scan.dll" without quotes. Using this, you should be able to prevent the scan.dll file from running, as well as keep it from fixing itself.
Comments and critisism are appreciated, so long as they are not "zomg u no listen 2 demunkoongah, u gon get teh banstick".
