It's installed on the machine I'm using now. Seems very discreet compared with some, not hogging the system to do all its folderol and getting in the way of other applications. After others of my experience, I like that. That alone makes me look favourably on it.
Whether it's effective is a bit harder to say; I'm not aware of having been hammered by anything but there are several layers of security between me and the outside world. NOD32 is one of the inner layers and hasn't logged a threat yet (and anything I install locally has already been through my own paranoia filter, which doesn't appear to have failed me yet).
And since I had nothing to do with the purchasing, and since that varies from region to region and distributor to distributor the quality of same may well also vary.
Okay, I set a manual scan running while I composed this; only 57k files on this machine, and it covered them in six and a half minutes.
