Hi Sarif,
 
 This message means the FortiGate AntiVirus detected a virus coming from your machine.  This means at minimum some UTM is enabled, but more importantly your machine is likely infected.  There' s a small chance it' s a false positive, but usually that is a big warning sign.
 
 Once you have determined your machine is free of virus (use a couple of scanning tools to be sure), try again.  If you continue to face this issue, please open a TAC case.  Include the following:
 
 1.  Backup of system config
 2.  Diag debug report / exe tac report
 3.  Packet capture from your machine and/or on the FortiGate when the issue is occuring.
 
 I am confident they will get you fixed, and probably with a lot less back and forth questions than I would have since they could see your entire config.
 
 Cheers!
