Remote Control Software

After over an hour on the phone last night trying to help my brother remove viruses and spyware from my nephew's laptop, and trying to talk him through changing some settings, I've come to the conclusion that I need some way to remote his laptop.

Of course, I've heard of Go To My PC, but I'm wondering if anyone out there has used it, and what your opinions are. Also, if you have any suggestions for any other remote software, I'd be grateful.

It's either that or drive 4 hours to work on his laptop every week until I break him from downloading stuff.

Edited to add: I'm also going to check his history, and maybe adding Net Nanny if I find he's going to some types of websites.
