How to secure a PC that is used by people who know very little about PC?

Hi friends.

As title says, how do I secure a PC that is used by people who know very little about computers? Myself, I would use common sense a lot and that would be 90 % of my protection - but how do I for example secure my parents computer? Antivirus, firewall, on demand malware scanner (I do not know any good real time one). Firefox with necessary addons, auto update. Attempts to tell them to be careful, some are esaier to understand - for example they do not open unknown emails and I am teaching them more and more daily, but it’s hard for them as most of you probably know. Anything else?

Have a look here for general pointers http://www.geekstogo.com/forum/index.php?autocom=custom&page=How_did_I

I would also recommend a lifetime licence for MBAM about $25.00 - It then becomes install and forget, set up daily/weekly scan, auto update then no more user interaction
