this might be caused by a virus already in your computer witch just wanted to get access to your computer and start doing what it wanted (might be from before in the computer in other words i dont know i just make a guess)

if it is a toolbar he must unistall it from the computer
go to my computer and find this http://prntscr.com/3wn4p1 ( i dont know how it calls it in england language i got my pc in greek to be able to use it easier)
it should open this in windows 8 http://prntscr.com/3wn4z6  or in older windows versions should open something looking almost the same with this
now find if there really is a toolbar or any other idiotic programm that u downloaded with something else u wanted and click on it and then click to delete it
i cant help further with this but u should be able to find it and do that

Maybe a stupid question but did you try pressing Left ALT Key and P Key in-game?
 
Since the logs seem fine you just need to use the shortcut (ALT+P) to activate the mod
 
Keep the peace,
