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.
This version introduces a revised user interface, an application filtering module, an updated anti-virus engine, and a vulnerability scanner. The main window separates settings in four categories, compared to eight in its predecessor. A status bar changes colour (green, yellow, and red) to reflect overall program status and flashes to divert attention when needed. PC Magazine also noted pop-up notifications were kept to a minimum.
Kaspersky claims the core anti-virus engine was revised to increase scan speed. PC Magazine found an initial scan took over two hours, however subsequent scans took two minutes to complete. However, malware detection was relatively low in comparison to other anti-virus applications tested. Out of 650 thousand samples, version 8.0 detected 95.6 percent. The top score was around 99 percent. Using two-week old signatures, version 8.0 detected 52 percent of viruses in a different set of samples. Kaspersky also blocked about 60 percent of malware based solely on behaviour. The top performers scored 55.3 percent and 80 percent respectively. Version 2009 detected 98.1 percent of adware. However, PC World noted to achieve that kind of performance, users will have to modify program settings. On default settings, KIS allowed Zango to install. To block the installation, users must enable KIS to scan for "other malware".
The Security Analyzer looks for operating system and program patches. It also looks for vulnerable system settings, presenting users with a list of recommended actions to prevent malware from gaining access to a system. However, PC World criticized the amount of computer jargon used and lack of information about how adjust settings appropriately. On the other hand, PC Magazine found the feature straightforward, and often the solution involved downloading and installation an update.
KIS uses a whitelist by Bit9 to classify trusted and malicious programs. Malicious programs are not allowed to run at all. Unknown programs falling in between the two categories are restricted in the actions they can perform. Its firewall blocked all attacks in PC Magazine testing. Phishing protection was introduced in this release. Testing by PC Magazine found the feature blocked 44 percent of phishing URLs. Internet Explorer 7 blocked 67 percent of the URLs, and Mozilla Firefox blocked 81 percent.
Spam filtering now integrates with Mozilla Thunderbird and scans NNTP traffic. Spam can be automatically diverted to its own folder. When using an unsupported e-mail client to download POP3, IMAP or NNTP mail, Kaspersky will still generate a report of all messages. However, in an unsupported client, there will be no toolbar nor will the program classify any messages as spam in the client itself.
