Following a recent security breach I checked out security with an expert in the field and he uses and suggested that I install Norton antivirus, so I purchased Norton internet security 2007 and I am happy with it.

The cost was A$60 but I got it for A$50 from a local computer market, with a one year subscription.

A week later at the market I came across a 1 gig flash or pen drive (Laser rundisk) selling for A$20 with a small free disc containing six months of Norton antivirus!
So I could buy two of these and not only get a 1 year subscription but also get two flash drives, And have A$20 left over.

If anyone is thinking of getting some security it may be worth looking at this method and not only save some money but get a couple of flash drives as well!!
Sounds good to me.

EDIT: The company who sells these flash drives is www.mrcdr.com.au and the email is sales2@mrcdr.com.au
I have mentioned to them that I am putting a link here for anyone who cannot get these locally and may like to order by post. hope this helps anyone who has any trouble finding one
I have no connection to these people except that I have purchased from them in the past and found them to be reliable.
