Also don't let that mcafee deal sway you. Mcafee is almost as bad as norton. The firewall is fine, but everything else is subpar and completely anti user friendly unless you pay for the full suite of options. It will not say you are protected and will remind you every hour unless you have everything. Then if it finds a problem, it says click here for more information. Then it tells you it needs your actions or something to continue but doesn't what the problem is or how/where to deal with it.
The only anti virus that is worth paying for is kapersky IMO. Friend has it and he's never had any problems and you hardly ever notice it. Although I run AVG and Comodo (both free) and with those and some basic internet smarts there is really no need for a paid virus scanner.
