What antivirus that is very effective?live update

I use AVAST! (arrrrr!) as I like pirates. I'm very happy with it.

Norton is *awful* - my Dad and I both found that one week before our subscription's were about to expire we mysteriously caught viruses and Norton saved the day. The particularly odd thing was that I wasn't even conline anywhere near that time... I've heard rumours that they do include a virus in their product to effectively bind you to them, and although my experience would back it up I can't say for true whether it is, or was, true.

ETA and I used to use AVG - never had any problem with it, but according to other half and his techie pals it wasn't staying as up to date as it could have been. That was a couple of years ago though, so can' say anything about it now.
