I'm running NSW '02 along with AVG from
www.grisoft.com on an XP notebook
and a desktop without any problems at all. I find that the extra NSW tools
do provide very efficient means in helping to keep my systems working
smoothly. Since NSW '03 is expressly made to be compatible with XP, I don't
how you could go wrong in deciding to use it. You don't have to install all
of the package if you don't want to but, I'd say that WinDoctor and
CleanSweep are a must to install. If you've not made a purchase already, I
suggest shopping for a bundled package that includes Norton's Personal
Firewall or Internet Security. It would be an excellent value.
As to NSW being a resource hog, that may be true in some instances. However,
I ran it an XP machine with a 766mhz Celeron processor and 768 megs of
memory with no ill effects. You don't mention the specifics of your system
but, if you have at least 512 megs of memory and a 766mhx processor or above
and XP is running well, I'd say you'll be happy NSW.
HTH,
