Edit: due to the exasperated response to this post, I want to make clear here that — as the post itself shows — it is not concerned with protection per se, but more concerned with detection rates. The "actual protection" layer in this setup is provided by Comodo Internet Security (or Firewall), and this program's settings are not discussed here at length.The use of more than one antivirus programs together can lead to trouble and/or reduced performance. This combo has shown to me no such issues, but you should be careful nonetheless. If you have a need or a desire for a combination of free antiviruses with fast real-time/on-demand scanners to achieve high detection rates, this setup is a possibility I have found.
-----------------------------------------------------------------------
I have tested this configuration during a few weeks and found it to work surprisingly well: three free Chinese AVs working real-time on top of COMODO Firewall (or in this case Internet Security with the AV real-time off). That's a total of 11 real-time engines! (Baidu's 3 engines [Baidu local, Avira local, cloud], Qihu's 3 engines [Bitdefender local, 360 cloud, QVM II machine learning / cloud], Kingsoft's 4 engines and COMODO cloud [that's 11, and with COMODO local on-demand you have 12]).The performance impact of this antivirus trio or quartet is average. If you need more performance, you can disable some engines and lighten other settings like real-time verification of documents and programs only instead of all files.
The real security of this quartet comes from COMODO Firewall / Internet Security, and it is enough to have CIS as it has excellent Firewall, HIPS and Sandbox, and also one of the top AVs currently.
However if you like your detection rates high, this quartet is hard to beat. You get exceptional detection capabilities with no conflicts (note the configuration spoilers, as you can see the proactive defense is off in all AVs, this job being left to COMODO).
* Partial because I'm not discussing anything else here in length, only the AV trio/quartet.

This whole system is still backed by Comodo Internet Security:
RAM usage (private working set):
Baidu totals less than 14 MB.
Kingsoft totals less than 16 MB.
Qihu totals less than 26 MB.
Comodo totals less than 9 MB.
Full AV Combo totals less than 65 MB.
Note: average idle RAM usage on a 2 GB Win 7 x64 machine.
