How can I unstall/install 2009 because of pc freezes up?

What can I do about my machine locking up after installing 2009 with spy sweeper

What a great way to protect the computer as soon as turn on the machine and the screen loads the machine freezes. I have to keep turning off and on the machine then finally I can use it.  ( I have to hold down the power switch, I can’t get to the task manager)

 

The machine is a new laptop with Vista when I purchased the machine a trial Norton version was installed, then I transfer my subscription over. 

Then I installed spy sweeper like everyone else I had no problems, now like everyone else the machine freezes up. after downloading the new version 2009

I see where people have uninstall and reinstall Norton 2009 and Spy Sweeper, however I not sure if I can?

When installing spy sweeper I was provided a link to download the software and I also downloaded Norton upgrade by a link.

Not having the cds I’m lost

Can anyone help me out!!

Thank you
