There are three ways to enable/disable IWSVA Web scanning:
            
               - 
                  
                  From the main IWSVA menu, click Summary, then click HTTP(S) Traffic: Turn Off (stops all Web traffic) 
- 
                  
                  From the main IWSVA menu, click HTTP > Advanced Threat Protection > Policies and then disable the checkbox before Enable virus scanning 
- 
                  
                  Open a terminal and issue the following command (stops all Web traffic): /var/iwss/S99ISproxy stop 
The three methods are synchronized. Upon the next screen refresh, IWSVA reflects any
               changes made using one method in the others.
