Spyware Blaster 3.0 Downloading Troubles

Hi...
I had a lot of trouble downloading the new version of spyware 3.0. After trying everything, I finally redirected the new version of spyware onto another location in my computer, and I finally able to download. The problem is now, I have two versions of spyware on my computer, 3.0 and 2.6.1. Unfortunately, the 3.0 did not simply "add on" or update the previous version. Help How do I get the old one off so that I do not cause any further conflicts?
Thanks!
