Looking for an Online Computer Support Service for My Wife

I have a good understanding of operating systems, specifically Windows, whereas my wife is less familiar with it. Whenever she encounters any issues, I play the role of her knowledgeable companion. Mockingly, I tell her that she will be in trouble when I'm not around, and she acknowledges this. Hence, I am currently searching for a 24/7 service that my wife can rely on to address her computer problems remotely. I have been looking into HP's "Smart Friend" program but there are mixed opinions about their customer service quality. Does anyone have any insights on this?
