I want a spyware doctor registration key

I believe they provide one for free with every copy you buy.

Its normally $30 but can be found for $25 here and there...

Using good tools to protect your computer is a great idea. Glad you're doing it!

If you are expecting someone to provide you with a key so you can pirate use of the product you will not find help here. This site does not condone and definitely doesn't support, illegal activities.
