Hi,
Netsweeper does not have a separate module or 'add on' for anti-malware capabilities, but provides these capabilities as a standard part of our web filtering. As part of our categorisations, we include the categories of "Adware", "Phishing" and "Viruses", and these categories are dynamically updated by the browsing patterns of the entire Netwsweeper user base (of more than 100 million).
The Netsweeper AI engines evaluate the content of requested URIs by applying behavioural, reputation and signature-based analysis.
In practical terms, this means that (assuming the appropriate categories are defined as 'blocked'), Netsweeper will block URIs that are identified as containing malware or other web threats.
