Antivirus Software

Due to the large number of TCP connections generated during a scan, some anti-virus software packages may classify Nessus as a worm or a form of malware.

If your anti-virus software warns you, select Allow to let Nessus continue scanning.

If your anti-virus package gives you the option to add processes to an exception list, add nessusd.exe, nessus-service.exe, and nessuscli.exe.

For more information about allowlisting Nessus folders, files, and processes in security products, see File and Process Allowlist.
