In 2005, two critical flaws were discovered in Kaspersky Anti-Virus. Īlso, Kaspersky, like the majority of its competitors, is incompatible with many other anti-virus and anti-spyware software. These missing features include a personal firewall, HIPS, Secure Keyboard, Anti Spam, AntiBanner and parental control tools. Kaspersky Anti-Virus lacks certain features found in Kaspersky Internet Security. It also scans incoming instant messenger traffic, email traffic, automatically disables links to known malware hosting sites while using Internet Explorer or Firefox, and includes free technical support and free product upgrades within paid-subscription periods. In addition, Kaspersky Anti-Virus prevents itself from being disabled by malware without user permission via password access prompts upon disabling protection elements and changing internal settings. Microsoft Windows users may download an antivirus rescue disk that scans the host computer during booting inside an isolated Linux environment. Kaspersky Anti-Virus features include real-time protection, detection and removal of viruses, trojans, worms, spyware, adware, keyloggers, malicious tools and auto-dialers, as well as detection and removal of rootkits.
