After performing "fixed" action, you can view the "fixed" security event by going to Response > Threat Response > Security Events > Fixed. Select the security event you wish to restore or unquarantine, then click "Restore", so it will restore to the file location.

FYI, Sangfor ES will quarantine malicious events, but will not automatically delete the files (including malware, virus, etc), until user selects a security event and click "Delete".

You can configure traffic profiles and traffic rules in traffic policy view. A traffic profile specifies the guaranteed bandwidth and maximum bandwidth.

Viruses, Malwares like the activator will be deleted instantly and will not be quarantined so you have no option to unquarantine it. That is the behavior of Sangfor ES and only the not so malicious will be quarantined.

In order to  repair it,  go to the security event tab, then  click the quarantine file and click "repair" then wait a few minutes to complete

It will be deleted once you click to fix it since it is an activator and the appliance will threat it as malware.

To repair it click the security event, then on the security events tab click the quarantine file and click "repair" and wait until status is complete
