|if you are getting a message when trying to stream videos online about troj/rustok-n
or are having problems with troj/rustok-n and winiguard alerts or pop ups, try using malwarebytes.
it only took me a few minutes to rid my computer of this annoying problem for free. i tried using true sword, cc cleaner, norton, avast, and spyware doctor. none of those seemed to detect it or help solve anything.
hope this helps
