Kaspersky Lab provides downloadable removal tools, product upgrades, antivirus and antispam databases, extra secure databases and product documentation on our website. It is essential to update antivirus databases on a regular basis. If you do not do this, your antivirus program will not detect new malicious programs. This is why we release updates every hour, to ensure that users are protected against the latest malware.
