How do you know it did not work on my system?
I installed the software in Vista compatibility mode and it worked just fine. 
Now I will uninstall it and turn off Securespot as I justed wanted to see for myself if it was really an issue affecting all people or perhaps just you.
Thats how I installed it as well, in fact it's the only way it will. And you bought securespot just to try this out? Besides, like I said it worked before on my wifes EeePC and my Dell with XP and Vista. Loaded 7 fresh(no upgrading) and it didn't work.
And how many websites did you try? Some loaded without a hitch, some just crawled and others wouldn't load at all.
If you'd really like to give it a go, try Newegg which was one of the problem sites for me. Just try about 20 sites here and there and you'll see the difference.
