NIS 2003 Pro would be a better choice for Internet and Virus protection combined, NSW 2003 is great for overall system insurance for protecting loss of data and Virus protection combine
Oh and a solid Spam filtering program that will automatically delete anything not coming from anyone in your addy book. Also Ad-Aware Pro to keep things from the web and anything else from making modifications to your registry with active scanning. Startup Orginizer is also a good program to run resident because it allows you to control apps upon boot and also double check the registry for additions actively. SystemInfo2003 works great for controlling all loaded processes, releasing memory, killing process threads(active programs and such) and clearing the cache's, clipboard and so forth...
I remember a year or so back I mentioned all of the utilities I make use of and someone commented about it being over kill, but then again I have not had a virus, worm or trojan in years. Excluding my laptop which I loaned to my son Chris for a couple of days which he returned to me with a number of them on it. He also had run that freaking dll crack on msstyles and had the whole damn thing hosed up so I wiped the drive and burned the ghost back on it. I also created a basic user account for anyone who happens to have it loaned to them in the future, which will not include Chris for a while.
Kids can't live with em and you can kill em, whats a parent to do?
