I've just completed the full scan that John in K suggested and the good news is that it found one contaminated file and fixed it, the bad news is, I thought it had fixed the problem as it seemed ok until I just started to write this post and now it's hanging up and slowing down, even these letters are delayed between the time I hit the key and it gets on screen, so I am typing very sloooooooowly to try and finish this.    GOT THERE! lol
