I was checking out antivirus programs for 2015 at the PCMagazine website. I almost laughed my head off at the evaluation of Norton Security. True, it just barely came out. But according to the guy's OWN TESTING it detected only 28% of the malware until he tried to open the files up. He made a big deal about TrendMicro detecting only 60% of the malware before he tried to open up the files! According to his own testing Bitdefender and F-Secure were detecting 80% of the malware immediately, before he attempted to open up files.
He said that Norton has a different method of operation now compared to the other antivirus programs. It is now a cloud antivirus. But so is TrendMicro and Panda as far as I know.
And then he gave Norton a high rating. Above TrendMicro. And TrendMicro, in the guy's OWN TESTING, detected 80% of bad websites and Norton detected 51%.
I can't imagine any antivirus detecting only 28% of the malware. I bet Windows Defender detects a higher percentage than that. Sure, after the malware gets on the computer the behavioral detection kicks in (for Norton). But the malware is on the computer then. Other programs like Bitdefender were blocking far more malware. In the end, after behavioral detection, Norton Security was detecting 89%. But Bitdefender and F-Secure were blocking about the same amount (and TrendMicro also including behavior detection) and they were blocking more malware immediately, even before behavioral detection.
28% malware detection? I think I will pass on the Norton.
