Am I correct in assuming the only difference is that ZA Suite offers anti-virus (in which anti-virus seems to only be so-so from what I read)? If so, I assume you can install ZA Suite without the anti-virus component? The reason I ask is that my ZA Pro trial is about to expire and at Comp USA, can get ZA Suite for $9.99 after rebates. I am not a big fan of rebates and still have to buck up an initial $70, but this sounds like it might be worth it as opposed to paying $50 for ZA Pro. The only thing that is puzzling though is that the CompUSA flyer says the ZA Suite is from AvanQuest, not Zonelabs. is AvanQuest a distributor? Do I owe it to myself to try any other trial firewall software programs before committing to ZA? I am 90 percent sure I will commit to NOD32 as my anti-virus despite it's what I consider barbaric GUI.
