I cannot terminate cmdagent using killswitch at all.
Please, see my reports and pictures from military1
here. What operating system do you use? I suppose the results obtained strongly depend on what OS we are using: XP or Win7, 32 or 64 bit.
The original topic has been discussed at length a few times before. You cannot protect against kernel-mode termination.
Do you mean any protection software, not only Comodo? And again: is there a dependence on OS?
