USING HEURISTIC ANALYSIS
Essentially, the heuristic method analyzes the object's activities in the system. For this purpose, any script included in an
IM client's message is executed in the protected environment. If this script's activity is typical of malicious objects, the
object is likely to be classed as malicious or suspicious. By default, heuristic analysis is enabled.
Kaspersky Anti-Virus will notify you when a malicious object is detected in a message.
Additionally you can set the detail level for scans: Light, Medium, or Deep. To do so, move the slider bar to the selected
position.
To enable/disable the heuristic analysis, and to set the detail level for the scan, please do the following:
1. Open the main application window and click the Settings link in the top part of the window.
2. In the window that will open, in the Protection section select the IM Anti-Virus component.
3. In the Scan methods section, check / uncheck the Heuristic analysis box and set the scan detail level
below for the component selected.
