Compression Types

The Trend Micro NAS Security™ scan engine can extract and scan files compressed using any of the most popular compression types (listed below). Trend Micro NAS Security™ can also check for viruses being "smuggled" within nested compressions, for example, an infected file that is zipped, ARJ-compressed, MS-compressed, and zipped again.

The maximum number of recursive scan layers is 20.
