quad monitor purchase + overall comp protection

[imeasy2read]

i decided to just group my 2 questions im pretty new at this kind of stuff and i have next to no knowledge with comps other then some knowledge in poker(: im going for nova elite next year. 2morrow i should be recieving a quad 20 inch monitor from cinemassivedisplays.com im just wondering if anyone has purchased from them? im sure ill be spending all day figuring it out, but whats more important than that is my overall lack of feeling secure with my computers my laptop is just about finished after 8 months of use theres some sort of virus and god knows what else on it when i rarely use the internet with it besides poker so im curious what else can i really do besides a firewall, virus protection and spyware protection... since ive already been hacked and im not exactly loving the idea of risking as much as i keep on stars i have enough to play 5-10 as my base game but i prefer to start off mass tabling 50-1 or sngs attaining nova elite will mean next to nothing if by midyear i decide to keep even more on my account and finding out that instead of getting ebay, paypal hacked it turns out just a little bit worse... thanks for trying to make sense of this imeasy2read
