Actually I dont really rate any of the AV companies at the moment.
I certainly wouldnt pay for one as none of the paid for ones have anything on offer anything that actually works any better than the free ones. You only have to glance at the web to see millions of people having to upload Hijack This logs to manually diagnose virus/spyware issues despite having supposedly been shielded by all manner of AV/Spyware software.
But something is better than nothing so Avira or AVG do a half sensible job for free.
Steer clear of any add-on firewall package unless you actually understand what you are telling the firewall to do. All too often people install firewall products and then get bombarded by questions by the firewall asking whether certain processes or services should be blocked or not. Depending on the answers you provide you could be doing more damage than any threat you might have had. This is all too often the root cause of instability and no end of glitches and problems and sometimes these actions can never be ondone, not even after completely uninstalling the product.
ZoneAlarm is the devil incarnate imho and I suspect that it has wasted at least 1000 hours of my life over the years. I am now very reluctant to touch any machine that has any trace of ever having ZoneAlarm installed as It'll likely need rebuilding from scratch to get it fully stable.
So, unless you're an expert, keep it simple and stick with the Windows firewall (combined with a properly password protected and NAT'd router with WPA2 configured for its wireless)
As for spyware, Spybot used to be the killer app as did AD-Aware before it. Neither are effective any more and nor is Windows Defender.
My advice (for the moment) would be to keep it simple, Avira or AVG, Windows Firewall + (NAT'd router). On top of this I'd perform regular updates and scans using Malwareytes. Next month the rule book could be re-written and it'll be all change once more to different products.
The key thing though is to stop and think before doing things. Ask yourself, is that email genuine? Is that hyperlink really taking me to where it says? Is that pop-up really my AV product or a Windows system message or is it somethng that looks similar? If it looks at all suspicious, close it using task manager.
