A new year promotion and it seems like a good deal.
Award-winning antivirus.
Personally used it and I have no complain whatsoever. Hassle-free subscription renewal.
The cost is around AUD$20.14, however the credit card payment charge is in Euros ($13.05), something to take note.
Furthermore, before placing order, there is a section called 'Continuous Protection' , make sure you disable that. (Thanks to eddiet83)
I did this with them via PayPal last year and it was set at automatic renewal which charged me 69 euros. Just make sure when paying you go and turn that off because it took a month dealing with their call centres in 7 occurrences to get the refund
