1. Do you run any Torrents?
2. Is your OS "cracked"?
3. What did you find with Grif's help at http://www.cnet.com/forums/discussions/how-to-remove-pup-option-603542/#post-f742c795-5881-433b-a29b-6d758efe5cd3
Recently a few random key inputs go through without me actually pressing anything on the keyboard, even as I type this now random letters are added in a random spot on the post periodically.
I'm primarily using a razor black widow ultimate keyboard, I've looked around and tried a few things people recommended. I've updated drivers and pulled them back to previous versions, uninstalled razor synapse (someone said it might be a ghost macro I can't see, which is why I did this) and swapped keyboards. Obviously, none of these worked. This isn't consistent either, there will be a few hours where it happens every couple of minutes, and a few hours where it doesn't happen at all. If any more information is required I'll add it to this post
