I've been using NOD32 2.7 for a while with a router firewall on my desktop. I am going to be in a hotel with a wireless system and have to use my laptop (Vista operating system.) Will Smart Security be sufficient or should I install NOD32 and a separate firewall? Do I need a spyware program beyond Smart Security of NOD32?. Also, any recommendations on computer security for beginners. I don't understand many of the acronyms I see in the postings.
