Mac guy needs PC help

[plaster8]

I'm thinking about buying a PC laptop just for poker, as I'm getting tired of playing just the few sites that are Mac compatible.

But having been a Mac user for all of my life, I really have no clue what I need to look for in a PC. Can someone tell me the basics of what I would need in terms of memory, processor, antivirus, firewall, etc.?

This would be a poker/Web surfing/word-processing machine only. No gaming or anything.

Thanks in advance for any help. I really have no idea what the hell would be adequate for these needs.
