Downloaded this mainly to remove the bs comet. Yahoo extension malware. Absolute joke. Sure it scans, the same as any other "malware" software, but basically ends there. Only allowing a quarantine of alleged infections or warning, but won't activate the actual Web protection until actual purchase. Sorry, but I'm not forking over $40 for a scape ghost scan/protection "sampler". Show me that it actually works, and THEN maybe I'll purchase.
