Require some info about BitDefenderAV 2013 and KasperskyAV 2013 Hi guys since my Avira IS license lapsed a few days ago, i am thinking about getting either BitDefender AV 2013 or Kaspersky AV 2013 ,both of which are available for quite a bargain in my country. But i have a few questions before making the purchase 1)Is BDAV2013 and KAV2013 compatible with Comodo Firewall(Proactive with Defense+ config)? 2)If there are any incompatibilities, what are they? and are there any recommended tweaks to solve them? 3)If the incompatibilities are unresolvable, would Online Armor Free be a good replacement as a firewall?
