Comodo IS (1 local AV, 1 Cloud AV, 1 Firewall, 1 HIPS, 1 Sandbox), all those for 20mb only (working set), hard to find better; maybe Panda Global.
Unfortunately RAM has very little to do with a program to be considered light. Especially on newer systems that have at least 2GB of RAM or more.
A light program doesn't slow down system response time, it doesn't make a difference how much RAM or CPU cycles it uses.
In Comodo IS case, it may only use a little RAM and CPU cycles, but it still puts a drag on system response time. Why? it is how the HIPS components work. Every process, handles, loaded memory modules, etc. has to get checked each time they are launched. This is what puts the drag on system response time because it pauses everything while checking.
Comodo IS is far from being light, sorry Comodo fanboys but it is the truth. This also applies to almost all full HIPS applications; Online Armor, Privatefirewall, Malware Defender, etc. (They are NOT light). If you don't believe try completely uninstalling them and use your computer with only basic AV and Windows firewall and feel the power of your system at work, disabling them is not as effective as completely uninstalling making sure to cleanup the boot drivers. Comodo is notorious for leaving behind boot drivers which still slow down system response time even after uninstalling. Some other security programs do the same.
I have tried just about every security setup and here is my findings according to system response time not counting RAM or CPU cycles:
1. Avira
2. Eset
3. Avast
4. Norton
5. AVG
This is an honest observation as most of you know I'm a Avast user but not a fanboy. I would like to see Avast run the lightest, maybe in the future. Of coarse I don't like Norton but it can run very light on some systems they have really made improvements in the last 3 years. Not the old bloatware Norton many older users were used to. It really is amazing how light Avira is even on old systems with slow processors and 512MB of RAM. Of coarse that is about all I like about Avira.
Thanks.
