Hi Brian,
Welcome to PCHF. We have a very knowledgable staff of techs here, and I think we will be able to give you a sampled opinion to your question.
Just for future reference, we have lots of forum topics here, and you want to find the closest match to your question when posting. I will be moving this thread to the Security/Anti Virus forum.
In regard to your question about which is better, there are a miriad of opinions. One caveat that I would bring to the table, is that Avast has a known conflict with Zone Alarm. It is something that has a work around, but it is good to know.
So we will open the forum up to comments - Which is better?
Looking forward to seeing you in the forums,
TTFN
