If you receive an error message saying \u201cIntegrity violation,\u201d or \u201cInvalid key file,\u201d or something like that while using Kaspersky Internet Security, Kaspersky Total Security, Kaspersky Anti-Virus, or Kaspersky Free (for example, after installing the product, updating it or updating your operating system), it is a bug\/glitch that we are already aware of and have a workaround for.<\/p>\n

To fix this problem, you\u2019ll need to reinstall your security solution. Here\u2019s how to do that:<\/p>\n

    \n
  1. Make sure you have your activation key on separate media, be it a piece of paper from the product box, and e-mail in your mailbox, your MyKaspersky account, or somewhere else. If you cannot find your activation key, follow the instructions from this article<\/a>.<\/li>\n
  2. Uninstall the security solution. To do that, open the Control Panel, choose Programs and Features,<\/em> select the security solution, and click Uninstall<\/em>. If that doesn\u2019t work, follow the instructions here<\/a>.<\/li>\n
  3. Go to the official Kaspersky Lab website<\/a> and download the installer for the security solution you\u2019ve been using.<\/li>\n
  4. Restart your computer<\/li>\n
  5. Run the installer and follow the installation instructions.<\/li>\n
  6. Activate the security solution using your activation key. <\/li>\n<\/ol>\n

    The problem should be solved. If for some reason it persists or you have any trouble finding your activation key or activating the product, submit a request<\/a> to Kaspersky Lab Technical Support through the My Kaspersky portal, and include a detailed description of the issue.<\/p>\n

    Once we come up with a longer-term solution we\u2019ll update this post.<\/p>\n","protected":false},"excerpt":{"rendered":"
