Best Antivirus,Best Spyware,Best FireWall:

[zapperpost]

Antivirus -- Kaspersky Internet Security (or just Kaspersky Antivirus)
Antispyware -- PC Tools Anti-Spyware (or avast! antivirus v4.8 Professional)
Firewall -- BitDefender Firewall (or Kaspersky Internet Security)

I know all this because I tried them.

Kaspersky -- Best at all
avast! -- General protection for great price
PC Tools -- I hate it (varies)
ESET -- Fastest!
F-Secure -- Best at most
eSafe -- Best suspicious detection

Kapersky or ZoneAlarm for AV/FW, Ad-Aware for spyware

Kaspersky Internet Security is best for AntiVirus & Firewall.
Spyware Doctor is best for Spyware.
