By default, <strong>Kaspersky</strong> <strong>PURE</strong> scans bothincoming and outgoing emails. If you are sure that the messages sent by you cannot contain any dangerous objects, youmay disable the scan of outgoing traffic.To disable the scan of outgoing messages, please do the following: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 IM Anti-Virus component.4. In the right part of the window, in the Protection scope section, select the Incoming messages only option.SELECTING THE SCAN METHODScan methods consist in scanning URLs in IM clients' messages to know if they are included in the list of suspiciousURLs and / or in the list of phishing URLs.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. When usingheuristic analysis, any script included in an IM client's message is executed in a protected environment. If this script'sactivity is typical of malicious objects, the object is likely to be classed as malicious or suspicious. By default, heuristicanalysis is enabled.109
