When i install Kaspersky Personal 5.0.388,i get the message "The antivirus database is corrupted and has to be uptated in order to proceed. Would you like to do it now?" I press yes, but when the updates finish, i get the same message again. I have uninstalled and reinstalled but the problem still exists. The kaspersky icon in the taskbar is greyed, and whenever i double click on it to open the program, i get this message. The program never opens.
