Missing malware is normal and doesn’t mean the software is mediocre or badly developed. Specially when we are talking about 1 sample
I haven’t seen anyone not missing malware yet and if I download Trend Micro, it will miss hundreds (even though on other tests here it’s been praised). It takes a lot of time and digging to find a ZoneAlarm compromise (in total I have about 112 incidents blocked) whilst some others are getting compromised 5 minutes after installation so I think that’s worth something.
Of course, a good program control will prevent the damage and unfortunately as
@Decopi mentioned is missing. Hence many users are pushing to get it. We have to wait and see.
