Hello Comodo Lovers

I not sure that this topic is for this board or not! I'm sorry

I work with Lovely CIS (FREE) from v5.3 until v5.8 release!

After v5.8, Our old PC has been very slowdown with CIS specially with Defense+ and AV... e.g. when CIS have a detection, PC for some second stop working!!.... startup loading is very  ..... And playing movies is very 

After this effects, I decide to uninstall CIS, use Windows XP Firewall, install Dragon, use Comodo SecureDNS, HostsMan, Sandboxie Pro, MBAM and Sophos free AV as on-demand scanner instead of heavy CIS!

More info: 1GB RAM, 80GB HDD, AMD Athlon XP 1500+ 1.34GHz

Can you help me?

I think you should consider upgrading your PC.
For most users, CIS is not heavy at all.
But their setup is stronger than yours.

Check if "Enable adaptive mode under low system resources" option is turned on under Defense+ settings.
Try to clean up your system from registry errors and temp files, defragment your HDD.

If this doesn't help, then make a fresh install of Windows and all your software.
Or restore system backup if you got one.

Check if "Enable adaptive mode under low system resources" option is checked under Defense+ settings.

Unchecked 

Have you tried to make fresh install of Windows and all your software?

Yes!

My PC: 4GB RAM, 500GB HDD, Intel I5 Core, 2.40 GHz. And even I at times feel when AV scan files it is lagging. And I do take care of my PC a lot.

You could try the low CPU config in this FAQ: Solving high CPU problems.

Try avast (free version, especially as we only need one of the features).

I would say, its a program like comodo describes an antivirus:
Resource useage like a 3rd line of defense,
statefull (it really follows this concept).
Also a lot of settings for you to choose.

While installation you can decide which aspects you want to install.
If you want to replace comodo ANTIVIRUS, you dont need to install much of the features.
Just the antivirus part (data system protection). You should still have comodo firewall and defense+. Uninstall the comodo antivirus first.

Its the best combination that i ever found regarding to resource useage.

DONT forget to make the settings!

mine is less powerful than yours , and i dont have any lag or slowdown, i run CIS + EAM full  + Webroot SA. (all of them tweaked to run together without any conflicts, EAM & WSA being companion AV)

you should disable useless services, autoruns, etc..., check my guide:

The CIS AV tends to slow down my netbook (Atom dual core, 1 GB RAM and XP)i when updating or slow start of applications. I have seen it heavy on older single core P4 XP systems as well. In my view it is a bit heavy on older hardware.

I can also see occasional slowdowns on my old single core Athlon 64 3500+ with 2 GB of RAM, but I have not seen slowdowns on systems with less RAM but with dual core processors.
Looks like Comodo really likes having at least 2 cores.
