still the best all in one. Only disadvantage to bitdefender is the number of running processes: BitDefender 9 Internet Security: ==================== Process...............Working Set ==================== bdss.exe..............21,232 xcommsvr.exe.......3,124 bdnagent.exe............920 bdmcon.exe..........16,324 livesrv.exe..............4,392 vsserv.exe............18,116 bdoesrv.exe...........1,640 ==================== TOTAL...................65,748 ZoneAlarm Internet Security Suite 6.1.737.000: ==================== Process.............Working Set ==================== vsmon.exe............24,472 isafe.exe...............10,992 zlclient.exe..............4,296 ==================== TOTAL...................39,760 ZoneAlarm SecuritySuite used less processes (3) and less total ram (40MB) however its a bit more buggy and the anti-virus doesnt see to detect as much. It does have better web filtering, but i reccomend K9 for that. Both are good programs though. screenshot: just want to add i dont actually use antivirus or firewall software, because i dont get viruses, spyware, etc. I do test them though before i reccomend them to others.
