A D V A N C E D A P P L I C A T I O N S E T T I N G SCHANGING THE SCAN MODEThe scan mode is the condition, which triggers File Anti-Virus into activity. By default, <strong>Kaspersky</strong> <strong>PURE</strong> uses smartmode, which determines if the object is subject to scan, based on the actions performed on it. For example, whenworking with a Microsoft Office document, <strong>Kaspersky</strong> <strong>PURE</strong> scans the file when it is first opened and last closed.Intermediate operations that overwrite the file do not cause it to be scanned.You can change the object scan mode. The scan mode should be selected depending on the files you work with most ofthe time.To change the object scan mode:1. Open the main application window.2. In the top part of the window, click the Settings link.3. In the left part of the window, in the Protection Center section, select the File Anti-Virus component.4. Click the Settings button in the Security level section in the right part of the window.5. In the window that will open, on the Additional tab, in the Scan mode block, select the required mode.USING HEURISTIC ANALYSISDuring File Anti-Virus operation, signature analysis is always used: <strong>Kaspersky</strong> <strong>PURE</strong> compares the object found with thedatabase records.To improve protection efficiency, you can use the heuristic analysis (i.e., analysis of activity that an object performs in thesystem). This analysis allows detecting new malicious objects which are not yet described in the databases.To enable or disable the heuristic analysis:1. Open the main application window.2. In the top part of the window, click the Settings link.3. In the left part of the window, in the Protection Center section, select the File Anti-Virus component.4. Click the Settings button in the Security level section in the right part of the window.5. In the window that opens, on the Performance tab, in the Scan methods section, check the Heuristicanalysis box and specify the detail level for the scan. Uncheck the Heuristic analysis box if that scanningmethod should not be used.SCAN TECHNOLOGYIn addition to the heuristic analysis you can use special technologies, allowing to increase the objects scan speed byexcluding the files that have not been modified since they were last scanned.To enable the object scan technologies:1. Open the main application window.2. In the top part of the window, click the Settings link.3. In the left part of the window, in the Protection Center section, select the File Anti-Virus component.4. Click the Settings button in the Security level section in the right part of the window.5. In the window that opens, on the Additional tab, in the Scan technologies section, select the required values.95
