Bruce, I am not a pro of any sort. I was advised to get Hitman Pro for protection a year ago. So I did. It seemed to work very well until the last two months. Now it would run but never finish it's job. I have deleted it. I have no idea what a rootkit is. Common knowledge is that any five year old can do all these things. I have no access to five year olds, so I make a lot of mistakes.
