new XP install required programs

Here's a list of what I put on a clean install:

firefox getfirefox.com

and the following from download.com
avg free (antivirus)
lavasoft ad aware (antispyware)
spywareblaster
zone alarm (firewall)

all are free...and all are unnecessary for OS X users! It's lame that you need to update 3 programs to keep XP running well.
