The other night I was doing something on the pc off-line (think I had just gotten off the net after some forum surfing)and all of a sudden Comodo pops up an alert smack dab in the middle of my screen (not in the lower right corner as usual) saying something to the effect of "A Shellcode Injection (no further specifics) was being attempted and what to do, choices were Terminate or OK. First thought: Uh, Oh. 
Well, I knew the mere fact the alert was center-screen in my face wasn’t a good sign ;). I also knew that shellcode injections are a VERY BAD thing (understatement intended), so I clicked Terminate. The PC immediately froze up. Waited a few minutes and eventually just had to power the thing off at the button as I could not even invoke task manager. At reboot, I checked & D+ had logged & blocked the attack. But nothing regarding this event appeared in my WinXP Event Viewers (that I could see). I immediately did all my security scans which all came up with nothing infected, so I presume Comodo’s D+ BOA protection saved my A#$%! THANK YOU, THANK YOU, THANK YOU, Comodo developers, for the wonderful new Detect Shellcode/Buffer Overflow Attack feature in Defense+. (:CLP) :BNC
