XP Woes : Laggy System

Hi guyz I'm facing a strange problem
My XP windows lags before executing anything
I'm on C2D with 2 Gb DDR2 800MHz running in realtime Avast & ZoneAlarm Pro

Anything I double click isn't opened instantly but after few seconds as if system is jammed
All inputs appreciated
BTW i've tried all type of registry defrags & compressions & removing temp files
Even I've tried optimizing services but in vain

Have u scanned with antivirus & antispyware, do a full scan.

And don't use zonealarm (My opinion) or remove it from startup & see what happens.

Try system restore if you are out of options. use COMODO firewall the best around now.

M

Clean system RAM

Remove Zonealarm and go for a scan with: *www.superantispyware.com/download.html

Can't remove ZA guyz
Comodo is free but I don't prefer it because I'm not comfortable with it
Its too much advanced, with options messed up

(Don't Mind)
I don't think with that amount of Ram on XP system there should be any problem
No virus is there checked all processes

Can I Monitor time taken by my processes ??

disable some startup services from MSCONFIG and SERVICES.MSC

but only do if you are sure which one to remove

Does the system lag even if ZAPro is shutdown?

You can try:
1. Set ZAP to receive program updates manually
(Overview > Preferences > Check for Updates > Manually)

2. Set ZAP AntiSpyware's automatic update to manual
(or set it to update automatically every 24 hours instead of the default 3 hours)

3. Turn off ZAP's realtime AntiSpyware.

4. Using a pirated key with ZAPro v8.x, causes some system lag. Try a genuine key.

Try auslogics boost speed and view the tut forum and have a look on vishal gupta's thread.

I think if I would have pirated this thing then I must have gone 4 full security suite rather than ZA pro
I uninstalled it & now using Kaspersky . Shear wastage of money grrrrrrrrrrrrrrrrr...!!!

Just restore your system to the time when your pc was not laggy
