Found this one when logging out of my NAB online banking, an ad came up whereby you can get PC Tools Spyware Doctor or iAntiVirus free for one year, you can also get 33% off Spyware Doctor WITH Antivirus or the Internet Security suite and 50% off Zonealarm Extreme Security.
Your required to register, they send you an email with the download info and reg key.
Just downloaded and installed myself, all worked a charm.
+ve vote from me.. anyway, If im already using McAfee, does this offer has any use to my computer?
