Ad-Aware Free Antivirus + 10.0.186

The new owners of Lavasoft have revamped Ad-Aware to the point where it has almost nothing in common with its predecessors besides function. It's a good reboot, but it's not out of the woods yet.

A big reason that the new Ad-Aware stands a good chance of surviving is because it's finally a usable product again. Gone is the tripartite vertical sectioning, replaced instead with a more traditional layout. Not unlike the major interface change that Avast introduced for its fifth version, the interface's quirkiness has been replaced by usability. The interface is divided into three horizontal sections: the top contains navigation to Home, Info, and Options; the second shows you a large, protection status icon with links to dive deeper into recent protection on the right; and the majority of the interface offers additional protection tools such as gaming mode, firewall, and safe browsing.

ESET NOD32 Antivirus 5.0

Version 5 of ESET NOD32 is a solid, creative attempt to create a suite that adapts to a rapidly changing threatscape, with an emphasis on generic detections and the now-commonplace reliance on both cloud and locally stored detections. Where NOD32's bigger brother Smart Security 5 left us wanting more in the ancillary features department, the area that many don't consider "core" security, NOD32 strikes a perfect pitch between features, price, and effectiveness.
