If I install Windows Defender should I remove AVG and Zone Alarm from
my XP home edition?
No, definitely not. Each of the three is a completely different kind of
program, and you need all three types to protect you. Windows Defender is
anti-spyware, AVG is anti-virus, and ZA is a firewall.
In fact, you should install additional anti-spyware software. One
anti-spyware program is simply not enough. Note that Eric Howes, who has
done extensive testing on Anti-Spyware products, states:
"No single anti-spyware scanner removes everything. Even the best-performing
anti-spyware scanner in these tests missed fully one quarter of the
"critical" files and Registry entries" See

I would add at least one (and perhaps all three) of the following (all
free):
Adaware
Spyware Blaster
Spybot Search and Destroy.
