Is Toshiba a good brand of laptop?

I have a Toshiba laptop. It has crashed on me twice, and I'm beginning to think it's the computer and not the possibility of a Virus. I have Virus protection with Norton AntiVirus 2007. Can you recommend any brand of Laptop better? I use it as a home computer, have wireless internet, and on occasion lug it around with me when I'm out. I want something that isn't susceptible to crashing every year. Thanks. =)
