Commercial license expiration
When a commercial activation code expires (this type of code is valid for a year or more), Kaspersky Internet Security 2014 will continue working with restrictions (for example,
will stop functioning) and will not update databases of known threats. I.e. the application will continue to disinfect infected objects / filter spam, but with the databases which were downloaded on the last day of your activation code validity.
Even if you manage to download the databases manually and try to install these to the product, Kaspersky Internet Security 2014 will stop functioning at all.
You cannot prolong the license validity period of a commercial activation code by adding a trial activation code. No trial activation code can be added to the product once a commercial activation code was installed.
Trial license expiration
When a trial activation code expires (a trial activation code is valid for one month), Kaspersky Internet Security 2014 stops functioning (protection will be disabled and the databases will not be updated).
You cannot install two or more trial activation code on your computer concurrently/ in turn; as the validity period of another trial activation code will not either overlap or prolong the license validity period of the first trial code.
What to do after license expiration
To restore the product’s functionality when any activation code has expired you should simply add a new commercial activation code into the product. You do not have to reinstall the application.
