What should be avoided when using Smart Scan in a low network connectivity environment?

In low network connectivity environments, relying on the File Reputation service should generally be avoided because this service requires real-time access to cloud-based data. The File Reputation service assesses files based on global threat intelligence gathered from Trend Micro's cloud resources. If the network connection is unstable or slow, the ability to retrieve the latest file reputation information may be compromised. This can lead to situations where files that are potentially harmful could go undetected, as the system may not have current information to make an informed decision on whether to allow or block a file.

In contrast, options such as checking for localized threats, utilizing a Smart Protection Server, and performing manual scans can be executed with lower reliance on network connectivity. Smart Protection Servers can cache data and enhance protection in environments with intermittent connectivity. Manual scans allow for immediate assessment of files without the need for cloud communication. Thus, the most prudent approach in low connectivity situations is to avoid reliance on services that require consistent and fast network access, such as the File Reputation service.
