Kaspersky Anti-Virus and Kaspersky Internet Security since version 2009 force users to uninstall Spybot during the installation process, although there is no serious incompatibility yet known. The discussion was concluded in the Kaspersky forum, which said not to install Spybot at all. Kaspersky seems to be reluctant to fix the issue, despite receiving several complaints. Incompatibility between the products might occur when Spybot S&D tries to modify the hosts-file (if selected by the user during immunization), which Kaspersky will interpret as an attempt to harmfully manipulate the file. This can be circumvented by not immunizing the hosts-file in Spybot S&D.
