Pc-cillin is the least resource hog of them all-read this:

Panda causes about a 19% slowdown of your system and norton is about 5%. I read this article after I used all of this software and it completely backs up what I had encountered. After installing a 3.0 ghz 800 FSB cpu and an ASUS P4C800-E with dual SATA drives in raid 0- I'm sorry even a 5% slowdown is too much. I like speed and I'm not going to let some stupid $50 app slow my system down.
Panda's firewall is pretty slim when you compare it to Mcafee's or something like Zone Alarm. Download a copy of Zonelaram or Mcafee and you'll see the amount of options that are available- even norton has a better firewall. Every firewall roundup review I have read consistently shows Mcafee, Zonealarm, and Norton as the best. I've seen the most positive reviews for Mcafee. Panda's firewall was probably just thrown in there as well as PC-cillin. Pc-cillin probably has the worst firewall out of all of them and its what I use.
On the antivirus portion read this:

Your choice of antivirus software is good-Norton is definately the best when it comes to antivirus- just read virus bulletin's tests. PC-cillin is probably second, followed by Panda and Mcafee (If you're only comparing these 4)
That wierd explorer crash happened on three different pcs and it happenned with AVG as well so it is not a firewall issue. It happenned on my dell laptop and two of my custom machines I built. There was no other software installed except for chipset drivers, sound, video, and network. Three different motherboards with three different video, sound and network drivers? Its real time scanning. When I exclude my shared doc folder in PC-cillin from real time scanning it doeasn't happen. When I don't it happens.
I don't keep my computer on all the time because it would be like a dust farm in there.
I use third party pop3 software -enetbot- to download my aol email. Enetbot is the problem, not the antivirus software-maybe I was unclear. Based on that Pc-cillin was the best when dealing with another program binding to port 110. If you read my post you'll see that I said norton was actually compatible with enetbot, but Panda is not.
Hey- we all have different requirements when it comes to software- maybe thats why we have so many options.
