Webroot is the only antivirus I've ever seen lighter than ESET. However, it uses behavior and heuristics more than its signatures, which are mostly in the cloud. If you get stuck without Internet Connection, then you can only use the behavior blocker. Also, there are some ads to get you to do stuff, but not so intrusive. However, 1/2 of the bottom of the UI is dominated by the ad.
