You don't need to get it back. You need to get rid of the worthless Kaspersky product completely.
Remove "Kaspersky Security" by following the instructions on this page. If you have a different version of the product, the procedure may be different. The product includes a Safari extension that may not be removed by the uninstaller.
Back up all data before making any changes. Never install any "anti-virus" or "anti-malware" software again.
