I'm sorry, but if you are recommending ZoneAlarm for network security, you've pretty much negated anything else you may have to say on the subject.
I used to LOVE ZoneAlarm, but (just like uTorrent) the original devs sold the franchise. In very short order, the program started to approach MacAfee/Norton levels of dysfunction. Simply google "zonealarm (problem OR issue)" for a speedy education.
I definitely recommend Comodo for firewall/overall heuristic protection ("HIPS" module, not to be confused with AV heuristics), but MSE (Microsoft Security Essentials) or some other other AV is probably best for virus protection; Comodo's AV is sufficient, but not stellar. Luckily, you CAN do that! Use a different firewall (such as Comodo, which lets you install ONLY the firewall), and Avast!'s AV, for example, if you like their AV. Just about all of the protection "suites" have alternative downloads/installs that let you mix-and-match like this.
Regarding Win8 being "smooth and polished": Not even close. Just to mention one thing, using the Metro interface (as well as many standard OS features) with a mouse, rather than touch panel, is just terrible. There are many, many other glaring issues, not the least of which is the "accidental" interference with P2P we see here. Not a big surprise.
