anyone who understands how webroot works,which is sometime completely different from other company's, will trust them and i really hope that they bring something innovative to their zero day protection and detection rate with 2015 version because there are still some problems with the software itself like bad removal , real time protection, zero day malware detection ,... . but i trust them and their new way to handle a threat is the future of security software's .
i think webroot is the best cloud antivirus if you understand the way it works.
