这是给澳大利亚Westpac银行提供的12个月的免费试用，原文如下：
Westpac, in partnership with online security specialist PC Tools, is offering 12 months free access to the following software products to help keep you secure online. When you download the software, you can choose to purchase an additional 12 months protection upfront, or you can renew the subscription at the end of your free 12 months

方法如下：
1.点击该银行的网址
http://www.westpac.com.au/internet/publish.nsf/Content/WISE+PCtools+Security+Software
中的Download security software – Free for the first 12 months

2.输入用户名、邮箱、密码信息后，提交。
3.随后邮箱中会收到三款产品的试用序列号。注意这是专门给Westpac银行提供的特殊服务。

可以申请12个月的系列注册码，申请过程超级简单，只需要认识26个字母就一定行，刚申请成功，好象一个邮箱一组的。再试试看的说！  

感谢楼主，这个个人一直在用破解的，现在有正版的了。   

一次送下面这几个系列产品的注册码
==============================
1.Spyware Doctor with AntiVirus
2.Privacy Guardian
3.PC Tools Firewall Plus
