@brandonn2010: Sorry I was not here for few weeks. Let me answer some of questions one by one.
1. Panda had good detections, so also their cloud AV. But this is
not compatible wit Avast. Also it's cloud often experiences problem. It's
removal capability is not good. One of my friend got infected with conficker while using his PC offline (Panda Cloud AV offers
limited protection at offline), After connecting with internet and scanning it detected conficker but couldn't remove it even after several reboot
2. Who told you that software firewalls are no good anymore. PC Tools firewall that you are using is very good and has HIPS inbuilt. No need to install threatfire with it. You can read matousec review for PC Tools Firewall and Threatfire.

Immunet is good and compatible with Avast. It has very little problems with cloud. I am using it for some time. But being in beta phase it lacks some feature like right click scan feature and any other scan except quick scan. It also fails to detect threat on-access if it is not in system drive, there it detects on-execution. On system drive it scans on-access. Also its responce is faster than Avast. So, no conflicts. Some times it detects threats in Avast's temp folder where Avast uncompress files. But these can be avoided by adding that folder to exclusion. It is not true what
Tech said, Immunet's community is much larger and older since ClamAV joins with Immunet.
4. You can use the Spybot's immunization feature as an alternative to hostsman.
