HP or Toshiba Laptop?

My grandmother has a Toshiba and in the second year she has had it, it has been really slow and received tons of viruses, and she only used e-mail and some games. My mother has an HP and when I use it sometimes it works great. She has had it for 3 years now and it is wicked fast and I never seen it get any viruses. I recommend the HP. If you are afraid that it will overheat, purchase one of the fans that go underneath. They make a huge difference, I have one myself.
