Any PlusNet Firewall/Antivirus Promotions?

[#1]

Hi all!
I have just migrated from Pipex, where I had the use of ZonaAlarm Antivirus (i.e. firewall and antivirus) for £5 a year. I have been using this for several years and I am very happy with it. Unfortunately, I have just been notified that my license expires in 30 days. Does PlusNet have a similar offer for its customers? And if not, what free/cheap software would people recommend?
Cheers!

From previous experience around these parts people seem to like AVG Free for anti-virus. There is also a free ZoneAlarm firewall out there although personally I use Kerio personal firewall.

Thanks for this! I have used all of these in the past and it looks like I will again. Just wanted to make sure that there were no special deals from PN...

Stick with the free ones. They work perfectly well, and, even if there was a discounted offer, why pay when you can get it for nothing?
