File Anti-Virus: security levels - Kaspersky Lab

Kaspersky PURE 2.0
Scan methods of File Anti-Virus
By default, File Anti-Virus scans objects using signature analysis (bases with the description
of known threats and their disinfection methods). The component compares the object under
scan with the records in the base and defines whether the object is malicious. Since new
malicious objects appear daily, there is always some malware which are not described in the
databases, and which can only be detected using heuristic analysis. This method presumes
the analysis of the actions an object performs within the system. If its actions are typical of
malicious objects, the object is likely to be classed as malicious or suspicious.
In order to configure heuristic analysis, perform the following actions:
1. In the File Anti-Virus window go to the Performance tab.
2. In the Heuristic Analyzer section specify the detail level 1 for scan moving the horizontal
slider to the necessary position.
3. Click the OK button.
Optimization of files scan
To reduce the scan time and accelerate the application operation, you can configure scan of
only new and recently changed files, which were modified after the previous scan. For this,
perform the following actions:
1. In the File Anti-Virus window go to the Performance tab.
2. In the Scan optimization section check the Scan only new and changed files box.
1 The higher the detail level is, the more resources and time are needed for scan, however the more thorough the
analysis will be.
