@littlek,
Some scumware of that variety will fight back, or act like the cure is the real enemy. Don't you believe it (Especially if Timber liked it). I haven't seen that exact scumware; but used the bleepingcomputer tools on two others variations successfully on a friend and colleague’s tubes, and the instructions were spot on as well.
Good luck!
(Yay, I might finally get credit for answering a question!)
