For interest and information, I'm copying below a post I have made at https://discussions.apple.com/thread/3212743
I had Sophos antivirus installed, and I noticed that quite often in Activity Monitor it was eating up almost 100% of my processor. I uninstalled that and switched to iAntiVirus which, weirdly, is doing *the same thing* - again, in Activity Monitor a process called iavd going up to nearly 100%. In both cases I'm using the latest version.
I've seen a number of reports on these forums of this behaviour with iavd, but I can't seem to see any for sophos. But doesn't it seem odd that *both* of these av packages show the same behaviour, at least for me? Makes me think there is something up at the OS level…
I understand that the standard answer is 'you don't need av with a mac'. That's not how I feel about it. Tried ClamXav once, didn't like it much…
