Kaspersky Internet Security or KIS is an Internet security suite developed by Kaspersky Lab compatible with Microsoft Windows. KIS supports the detection and remidition of malware, as well as e-mail spam, phishing attempts, and data leaks.
Version 7.0 introduced a redesigned GUI. Components were renamed and reorganized; the Anti-hacker module was renamed to the Firewall, and the Anti-Spy module was integrated with the Privacy Control module. PC World described the new interface as "intuitive" and "great-looking".
Parental controls were introduced, with specific settings for different age categories, such as "child" or "parent". Within age categories are content categories, such as drugs or violence. Users can manually configure profiles. Filtering profiles can be associated with users. Since content is filtered at the network level, the feature will work with any Internet browser. The filter relies on a database of known URLs and can analyse websites in real-time. Attempts to access forbidden URLs are logged, and sites visited are tracked as well, raising privacy issues. Limits on Internet access may be set based on time, and chat rooms along with webmail sites can be manually blocked.
Spam filtering integrates with Microsoft Outlook, Outlook Express, Windows Mail, and The Bat!. E-mail content is analysed and scored, and e-mail with scores above two specified thresholds are either marked as "!!spam" or "??probably spam". The Mail Dispatcher feature shows subject and sender information for messages, and allows users to avoid downloading blatant spam by selecting which messages to download. The filter self-trains by analyzing incoming and outgoing e-mail not marked as spam, or by analyzing folders only containing spam or valid e-mail. Senders of verified valid e-mail are whitelisted. E-mail can also be whitelisted or blacklisted based on phrases present in the text. E-mail with non-ASCII characters or invisible text can also be blocked. However, version 7.0 had a relatively poor showing, misidentifying 30 percent of valid messages in PC Magazine testing. 30 percent of spam also made to the inbox.
Protection against data leaks was incorporated in this release. The suite warns users when programs attempt to access or send data from certain areas, such as where Internet Explorer stores webform information.
Malware protection was mostly positive in detection and disinfection tests by AV-Test.org. Version 7.0 detected 100 percent of wildlist threats. Using one-month old signatures and a set of new malware, however, detection fell to 14 percent. Files were scanned at 5.24 megabytes per second. Version 7.0 successfully identified all six actively running rootkits, four of six inactive rootkits, and was only able to remove two of six rootkits. The firewall correctly blocked all attempted outside connections, with a reasonable level of security when left on default settings.
This version drops support for the Windows 98, 2000, and NT. Windows XP Service Pack 2 is required, except in the case of XP Professional x64 edition. Vista is supported as well. RAM and CPU requirements are dependent on the operating system. 75 megabytes of free space, Internet Explorer 5.5, and Windows Installer 2.0.
