To check if your data may become publicly accessible:
The Data Leak Checker window opens.
Kaspersky starts checking the specified address. If the check reveals that your data may be publicly accessible, the application will notify you about it and display a list of sites from which a data leak could have occurred, the date of possible leakage, and the category of data that may be publicly accessible. Clicking a data category link will provide recommendations on how to minimize the consequences of a possible leak of this data.
Kaspersky lets you check for possible leaks of not only your own data, but from other user accounts that belong to your friends and family, for example.
