## Symptoms

- The SMB appliance detects and blocks a malicious activity of a host and reports it as "`infected`" or "`possibly infected`". However, the host was scanned and protected by an Endpoint protection (Check Point or a 3rd party agent) which did not find or block any malicious activity.

## Cause

The above symptom can be caused by the following causes:

1. The host tried to access a malicious site or download a malicious file, and as a result, the SMB appliance blocked that connection. Therefore, no malicious packets arrived at the host to be found.
2. The malicious activity, which the SMB appliance blocked, might have been a False-Positive.
