Hello,
I found, that there is wrong description for Proactive threat protection (Aktivní ochrana před hrozbami) in CZ version of SEP 12.1.4013.4013 client.
The description is: "Neposkytuje žádnou ochranu před neznámými hrozbami"
It means in english: "Does not provides any protection against unknown threats"
I think, that correct description in czech should be this: "Poskytuje ochranu před neznámými hrozbami"
It means in english: "Provides protection against unknown threats"
Please, correct this, because it is very confusing.
