PROBLEM:
When KAV (Kaspersky) is first deployed to an endpoint the Kaspersky UI is automatically set with a default password. If an end user tries to change certain settings on the Kaspersky UI or uninstall Kaspersky, the end user will be prompted to enter the password.
SOLUTION:
As a best practice it is recommended to change the default password to a custom password to avoid end users from uninstalling Kaspersky or changing the settings locally. A custom password can only be applied during the installation process of KAV using the VSA.
To do this, prior to installing Kaspersky, navigate to the Kaseya Anti Virus tab > Machines page. In here select "install" > "Install or Upgrade Anti Virus". This will open the window shown below.
In here select the "Advance Options" and enter a custom password as shown below. The password entered will then appear in the on the right pane after Kaspersky is successfully installed.
