That's why ZoneAlarm is so poor; it uses a very old Kaspersky engine. Without this, Zone could have dissapeared. It's useless without Kaspersky.strange that zonealarm has such low detection rates , even it does use an older kasperky engine , can someone elaborate why this is possible. AVG'S problem : zeroday component questionable , sometimes it does good , somtimes it does not , plus AVG relies heavilly on signature detection. even if if you tweak AVG to the max , its not much different than its standart settings!
