I would like to vouch for @Nic and webroot.
I bought the home user edition last year for my PCs at home. I even had a free access to Sophos AV due to an agreement acheived with Sophos when we purchased the Enterprise Console. I have yet to use Webroot in a business environment, but I can tell you it is hands down the best client for home users. Its lightweight and it never gets in your way like other home AV products.
@Nic is a pleasure to deal with. He went out of his way a few times to help me with a home product. How many vendor employees will take 20-30 minutes out of your day to help with a low cost home product? I have yet to find one other than Nic. He isn't pushy at all. He knows the product will speak for itself once you install the trial.
