Since moving to OSX I'm not "using protection" for the first time in years. However, I'm now sharing files (Word, Powerpoint, Excel) more often than ever between work and home, so I'm a bit concerned about this--and find myself thinking that I really need to start using one again.
Harv, until now, I've always used NAV, but got scared by all of the reports about anything Symantec and OSX. Sounds like you've been fine with it so far. I was glad to hear that. So far I've not read good reviews at VersionTracker about VirusBarrierX or NAV.
