After installing KillSwtich and opening it through Comodo ISP you get the chance of replacing the default task manager with KillSwitch through Options→Replace Task Manager.
After doing so, if you open KillSwitch through Ctrl+Shift+Esc, it will instantly close all opened programs—saved or not—and terminate explorer.exe.
This behaviour is presented as a feature on your website. But the violent nature of the termination—combined with the lack of any warnings about it on the first opening—made it much more dangerous for me than any “honest” virus or worm that I could’ve gotten infected with on my own.
Because of trusting Comodo with safety of its products, I lost more data today that I’ve lost to any other program—virus or not—in the past 5 or so years.
So my bug report suggestion would be: put a ■■■■■■■ warning before the first Aggressive Launch.
