Windows Defender will play nicely with Kaspersky, but KAV (and KIS) already have pretty decent spyware protection.

Uninstall ZoneAlarm firewall and get the free Comodo Personal Firewall instead, it's much better.

There isn't any need to switch to Kaspersky anti-virus as Avast! Home edition is good enough. Just make sure to keep Avast!, Windows Defender and Comodo active and updated all the time. You can also use the free McAfee Site Advisor plug-in for your browser (IE and Firefox), it will warn you of bad sites:

You may also keep a secondary anti-spyware to scan your system every week or so. I will recommend the free version of Super anti-spyware.

P.S.Never use more than anti-virus or firewall, they can cause driver conflicts.
