Information from the AV-Comparatives website.
They did a user survey.
There were 2,118 responses.
Q 10: Which type of test are you most interested in?
The Number One response was "on-demand malware _file
detection test_".
Q 18: What is important to you in a security product?
The Number One response was "good detection rate of
malicious _files_ without being dependent on cloud/online
connection".
Q 19: What should AV vendors try to improve more?
The Number One response was "improve _file detection_ rates
without support from the cloud/online connection".
Here is the AV-Comparatives statement about the 2012 participants:
"As Symantec Norton declined to participate in the _File Detection Test_, we will unfortunately not be able to provide our readers with any test results for Symantec Norton in 2012."
Now from the www.symantec.com website:
1) "Symantec acquired PCTools, a global provider of security and utility products."
Now consider this:
Symantec allowed PC Tools to participate in the 2012 AV-Comparatives test!
2) "Mt. View, Calif. – Sept. 7, 2011 – Norton by Symantec today released Norton Internet Security and Norton AntiVirus 2012 ... Norton Internet Security 2012 ranked first in overall performance testing by both PassMark Software and _AV- Comparatives_."
That press release was in September. And then Symantec -- with NIS 2012 19.1.0.21 -- participated in the On-Demand Comparative test, which was revised by AV-Comparatives on _September 27_. (To include newly released products, apparently.)
NIS 2012 19.1.0.21 finished:
14 out of 20 in the speed test
15 out of 16 in the false positive test
12 out of 15 in the total detection rate test
That was followed by Symantec announcing that they won't participate any more.
Reason given: because of the _File Detection test_!
NIS runs a File Detection test every time they run a background scan, lol.
And then that was followed by the virtually once-a-month release of new NIS 2012 versions noted in a post above.
Every word above is a statement of _fact_, not a subjective opinion.
