My first post is to say many thanks.

I have looked for a reliable anti-virus software for mac, I now realise there are dangers out there for the mac user and I prefer to protected now than suffer later. I have tried a couple of anti-virus software, one was easy on the system/CPU, but I was not convinced of it’s efficacy, the other from a well renowned corporate source, left my mac hanging ending up frozen.

So far Avast looks good to me.

Thanks again
