Twenty Reasons Not to Use Kaspersky
1. When Kaspersky cannot kill a virus, it will restart the system. After the restart, minor problems may cause some software to be unopenable, while major problems may damage the entire system.
2. When the system time reverts to the time before Kaspersky was installed (for example, year 2000, and Kaspersky was installed in 2007), Kaspersky will not open. If this time change was caused by a virus, then Kaspersky essentially self-destructs - it cannot be uninstalled or reinstalled. (This is a good method for viruses to disable Kaspersky, hence one of the reasons why Kaspersky might not be functional.)
