the real-time mode using the current (latest) version of the anti-virus da-
tabase.
V
Virus outbreak counter
– a template used to create and issue notifications
about a virus outbreak threat. The virus outbreak counter contains a set
of parameters that determine the virus activity level threshold, the distri-
bution method and the text of notifications to be sent.
Virus activity level threshold
– a maximum allowable number of events of
a certain type within a specified time interval; when this number is ex-
ceeded, the situation is classified as increased virus activity and a threat
of virus attack. This value is of great significance in the periods of virus
outbreaks as it helps the administrator timely react on the emerging
threats of virus attacks.
