IWSVA may trigger a detection for any of the following reasons:
            
               - 
                  
                  A virus, Trojan, worm, spyware file, etc. was detected 
- 
                  
                  The file was password protected, encrypted, or corrupt (unreadable) 
- 
                  
                  The file was compressed, and Block Compressed files is selected (HTTP > HTTP Malware Scan > Policies > [policy name] | Virus Scan Rule page) 
                     - 
                        
                        Compressed file contains too many layers compression 
- 
                        
                        Decompressed file size will be too big 
- 
                        
                        The decompression ratio of any file contained in the compressed archive exceeds the
                           limit set 
- 
                        
                        number of files contained in the archive would have exceeded the set limit down 
 
- 
                  
                  User has exceeded his/her bandwidth quota 
- 
                  
                  The file exceeded the specified maximum file size: (HTTP > HTTP Malware Scan > Policies > [policy name] > Virus Scan Rule) 
- 
                  
                  The client connection timed out 
- 
                  
                  One of the IWSVA pattern files contains an error (rollback to previous version) 
- 
                  
                  IWSVA installation topological is incorrect (traffic routing problem) 
- 
                  
                  Web traffic is turned off in the Summary page
