SING HEURISTIC ANALYSIS
Heuristic analysis is a special inspection method. It is used to analyze the activity of an object within the host system. If
that activity is typical of harmful objects, then such object will be recognized as malicious or suspicious with sufficient
probability even if the dangerous code in it is yet unknown to the anti-virus analysts.

You can select the level of heuristic analysis intensity:
light scan
– a quick check;
deep scan
– a thorough check taking more time;
medium scan
– an optimal combination of scanning speed and depth suitable in most cases.
If heuristic analysis reveals a malicious object, Kaspersky Internet Security will notify you about that and suggest
appropriate handling for the detected object.
