DACS' ethics aside I'm going to go on a limb to say that KillSwitch is a fantastic tool, of course NOT in the hands of a beginner. Pros (as far as I can see for now): Portable, no installation necessary. Ability to analyse a process all the way to infinity. . Ability to upload processes directly to virustotal or virusscan.jotti for a second opinion, beside Comodo's own, obviously. . You can "terminator" a process at a time. A user can terminate all unsafe processes at once. Quite invaluable for online banking. Somehow, similar to DefenseWall's own online banking mode. Rate all processes and gives them a rating of safe, unsafe, or unknown. Con(s) Thus far: Unable to display hidden processes on a 64bit computer. . At least for now. I think this is a great product to the quality and effecient level of ESET Sysinspector. What do you think guys? Thanks.
