Is it true?

Hello

I see many advertisements on the Symantec researching more about the product on the internet I found that the site of AV Test for example it shows only 4.5 to 6.0 protection.
This test is performed true? The Symantec support is outsourced really like Kaspersky reports?
I also noticed many people on the internet reporting problems with the enterprise solution seems small viruses that pass through it easily. Is it true?
While we trust that the test is really 4.5?
