about. As a rule, Kaspersky Anti-Virus detects unknown viruses con-
tained in objects using
heuristic code analyzer and such objects are as-
signed the suspicious status.

ing new records to the anti-virus database received by the application
from the Kaspersky Lab’s updating servers or from a network folder.
V
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.
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.
