Kaspersky Anti-Virus 6.0 protects PCs against all malicious programs, combining traditional signature-based methods (detection of viruses based on their descriptions) with proactive protection. Kaspersky Anti-Virus 6.0 monitors all critical areas of the operating system for potential threats, and can detect hidden code, such as rootkits; and ensures that data transferred to and from the computer is safe by scanning in real-time all incoming and outgoing emails, as well as files and web pages downloaded from the Internet. Additionally, the scanning speed of the new software, and the time taken to download antivirus updates, is faster than its predecessor. New to Kaspersky Internet Security 6.0 is a personal firewall, which controls data exchanged between the user’s computer and the Internet.
