New user for Norton Utilities 14.5

Hi,

I have been a user of Norton Internet Security for 10+ years. I always buy the annual updates. So just now I bought and downloaded the new Norton Utilities 2010 version 14.5.0.116.

 

The first thing I did was to run "Clean Your Registry". When I saw that it found over 700 registry issues I got nervous about letting it clean up and make that many registry changes. Is it really safe? Do I need to turn of Internet Security before I clean the registry and shut anything else down?

 

I have had no real issues with my PC (XP Pro) except that its been running slow and I am nervous about letting this app do SO MUCH.

 

Your thoughts?

 

thanks,

Steve
