hey Big Booger, I think its best to stay away from Norton Internet Security.  I like their antivirus program and all, but even that seems to take too much control of my computer at times, which I hate.  I now use AVG Antivirus which is really good so far and free.    THe Proximitron is a very small program which takes up very few system resources but Norton Internet Security on the other hand takes up much more resources especially if you dont have a lot of memory to spare.   No problem guys, i'm glad I could help out.      Bobby
