Web Antivirus tab

Antivirus > Configuration > Profiles > New or Edit > Protection > Web Antivirus

If enabled, Web Antivirus scans traffic that arrives on the user's computer via the HTTP and FTP protocols, and checks whether URLs are listed as malicious or phishing web addresses.

• Enable Web Antivirus - If checked, ensures security while using the Internet. It protects your computer against data coming into your computer via the HTTP protocol, and also prevents dangerous scripts from being executed on the computer.

Security Level

• Security Level
  • High - Set this level if you suspect a computer has a high chance of being infected.
  • Recommended - This level provides an optimum balance between the efficiency and security and is suitable for most cases.
  • Low - If machine operates in a protected environment low security level may be suitable. A low security level can also be set if the machine operates with resource-consuming applications.
  • Custom - When any other setting on this tab is changed, the Security Level is set to Custom. Reset the Security Level to High, Recommended or Low to reset options to their default settings.

Action on Threat Detection

• Select action automatically - If checked, automatically performs actions recommended by Kaspersky Lab. Once a threat is detected, the application attempts to disinfect the object. If disinfect fails, the application attempts to delete it. Suspicious objects are skipped without processing. If blank, protection uses the customized settings below.
• Select Action
  • Block Download
  • Allow Download

Scan Methods

• Check if links are listed in the database of malicious URLs - If checked, scans the links of email messages included in the database of suspicious web addresses.
• Heuristics Analysis for detecting viruses - If checked, uses heuristics analysis to identify the behavior of objects as malicious or suspicious, even if they are not yet identified an known threats in the signature database. This allows new threats to be detected even before they have been researched by virus analysts.
• Depth - Depth of heuristic analysis to use: Light, Medium, Deep.

Anti-Phishing Settings

• Check if links are listed in the database of phishing URLs - If checked, scans the links of email messages included in the database of phishing web addresses.
• Heuristics Analysis for detecting phishing links - If checked, uses heuristics analysis to identify the behavior of objects as malicious or suspicious, even if they are not yet identified an known threats in the signature database. This allows new threats to be detected even before they have been researched by virus analysts.
• Depth - Depth of heuristic analysis to use: Light, Medium, Deep.

Actions

• Limit web traffic caching time - If checked, limits the time allowed to scan each fragment of an object separately as it is downloaded. If the limit is exceeded for a fragment, the fragment is downloaded without scanning. If blank, fragment scanning is never skipped. In either case, the entire object is scanned once it is completely downloaded. Useful when you want to speed up scanning.
