Comodo Verification Engine is a free program helping all Web users separate the real from the fake. Verification Engine (VE) couldnâ??t be simpler: download the free application, then move your mouse over any logos or log-in boxes on a page youâ??d like to verify. If itâ??s the real deal, a green border will appear around your browser. (Or, if you prefer, you can program any .WAV file to play upon verifying a siteâ??s identity.)
