Focus software produces escan which is a firewall, antivirus, anti spam and parental control all in one for about a tenner. It has been running for about six months on a laptop and there have been no problems with any hackers or virus's. I bought it in Woollies but any where that sells Focus software should sell it. The license is for a year when it has to be renewed. The software runs in the back ground but only uses 32mb RAM to do this. Regular updates which are automatic. Apparently there is free telephone and e mail support.
