Currently I don’t like any of the common AV solutions, ClamAV is the best we have and has great signature based antivirus, with many excellent third party virus signatures (I even use it on windows). however ClamAV has no heuristic based capabilities which means it’s lacking quite a bit in that regard.

I really wish we had a decent hurestics based AV solution oriented to consumers but afaik none really exist that are any good.
