As you do not give much information about your system then not much help can be offered.
Outpost Free works well with avast!

okay
I am using
Microsoft Windows XP
Media Center Edition
Version 2002
Service Pack 3
Intel(R) Core™2 CPU

1.60 GHz,

I am using only one antivirus and windows firewall.
Can i use Zone alarm or other free firewalls without hampering my system files???
If yes, then which one would be better???
The one suggested by kenny is my favorit, almost fully automatic, not many popups
Online Armour
PCTools
Outpost Firewall Free
Comodo
ZoneAlarm

Avast 5.0.545 have many sheilds like network shield ,web shield,mail shield .Does these shields have any conflict with the above mentioned firewalls or do I have to turn them off???
???
no the firewalls above will not conflict with avast.
No. avast free antivirus won’t conflict with any 3rd party firewall.
Thank you everybody

I got tired of Windows 7 Firewall Control, so I decided to replace it with ZA.
ZA is more user friendly than W7FC.
Since I have a one year subscription of ZoneAlarm Pro for up to three computers,
I put it on both computers, XP & Windows 7 64bit.
ZA Pro is running smooth & quiet on both systems.
While ZA Pro offers more protection than ZA Free, ZA Free has never failed to protect
my computers, is ZA Pro really better? In other words, is the added protection of ZA Pro needed?
Avira is said to have more detections than avast!, but since avast! hasn’t failed me, is Avira better?
I’ve never needed the extra features of WinPatrol Plus.
Zemana hasn’t found any keyloggers on my XP machine. (Zemana doesn’t run on 64bit systems.)
The security combo of avast! 5, WinPatrol, and ZoneAlarm can’t be beat for ease of use, lite on
resourse use and excellent security. IMHO
