I've finally (& successfully) removed Norton Internet Security from my computer.
My computer seems so much faster without it.
Any suggestions on what I can replace Norton with?
I'm using XP w/ Firefox as my browser.

Are you looking for an Internet Security Software or an Antivirus Software? I am using NOD32 as an Antivirus Software which is really good. I have some friends using Kaspersky which they says is very good as well.

Kaspersky is as powerful as they come, but for most users it's just bloatware.
The more powerful an antivirus program is, the more it will hog system resources.

I find AVG to be good enough for what I need, and it's free.

I have AVG to and it works very good for freeware I have had no problems with it.

I use the E-Trust Armor products.
