Full Antivirus Protection Overview
A virus is executable code that infects or attaches itself to other executable code in order to reproduce itself. Some malicious viruses erase files or lock up systems, while other viruses merely infect files and can overwhelm the target host or network with bogus data. The full file-based antivirus feature provides file-based scanning on specific Application Layer traffic checking for viruses against a virus signature database. It collects the received data packets until it has reconstructed the original application content, such as an e-mail file attachment, and then scans this content.
The full file-based antivirus scanning feature is a separately licensed subscription service. Kaspersky Lab provides the scan engine for full file-based antivirus. When your antivirus license key expires, you can continue to use locally stored antivirus signatures without any updates. But in that case, if the local database is deleted, antivirus scanning is disabled.
 | Note: The express antivirus feature provides better performance but lower security. Note that if you switch from full file-based antivirus protection to express antivirus protection, you must reboot the device in order for express antivirus to begin working. |
