    Some (or most :p) might recommend Kaspersky or Avast, I'm an AVG user myself and found it to be the least in resource hogging (don't know about registry keys though). :)

    Not sure about the registry keys.

    I'm currently using Kaspersky and it works pretty fine.

    What is NOD32? :p

    Nod32 hands down. Not only does it consume the least and takes up the least space, it's also got the best proactive defense and is probably the fastest on-demand scanner available too (consistently for several years).

    Kaspersky has made a ton of improvements over its last 2 versions in footprint (anyone remember how bad it was pre version 6?), although it has always been #1 or near the top in terms of known viruses and still probably is. Still, Kaspersky 7 isn't as compact as Nod32 3.0, especially if you turn advanced heuristics way up (Nod32 manages to do this without slowing the system down noticeably and still get better results than Kaspersky :p).

    For the free ones, Avast, AVG and Antivir (Avira) are all quite lightweight (although none of them compares to Nod32 in terms of efficiency or results). I actually disliked the drain each of these free ones put on my system.

    AOL Activevirus shield mentioned above is nothing more than a truncated version of Kaspersky 6.0, and the new Aol antivirus is just mcAfee.

    From my experience I have to say that it's a tie between Avira Antivir and AVG. Avast consumes about 5 MB more RAM than the other two, but that would be a minimal difference that you'll hardly notice these days with 1 or 2 GB of RAM becoming standard. As for the registry keys I would guess that Antivir or AVG would have the least, as they're quick to install and uninstall. Think about Norton! :D
