Broken or expired certificates issued by Kaspersky Anti-Virus to your Internet browser may cause unwanted warnings and error messages, and it may eventually slow down your Internet connection. There is no official feature in the program's interface that allows you to remove a problematic certificate. However, you can use your file manager to navigate to the location where the certificate you want to remove is stored and then delete the file associated with it.

Point your mouse to the top-right corner of your screen to open the "Charms" bar. Press the "Search" button.

Type "Computer" (without double quotes) and select "Computer" from the list of results.

Navigate to "C:\Program Data\Kaspersky Lab." Type "cert" (without double quotes) in the search bar. Select the folder named "Cert" from the list of results to open the location of the Kaspersky certificate files.

Delete the file corresponding to the certificate that you want to remove. This file contains the name of the certificate and has the ".cer" extension.


The steps presented above are applicable to Windows 8 and may vary with older versions of the operating system.
