Fast and Customized Archive Scanning for Over 30 File Types
Detecting threats in compressed files, such as .ZIP or .RAR, can be difficult due to their large file size and ability to mask hidden threats such as archive bombs (malicious files designed to crash anti-malware programs). Archives can be scanned for threats using either unextracted scanning (scans entire archive as a whole) or extracted scanning (scans each file within an archive individually). Metadefender Core supports both scanning methods and offers fast processing of archives by allowing administrators to perform archive handling once for each file type instead of allowing each individual anti-malware engine to use their own archive handling methods. Additionally, administrators can customize the way archive scanning is performed to avoid threats like zip bombs.
Catch Threats Hidden Within Archives
Scanning an archive as a whole may be faster, but extracting files and scanning them individually often reveals hidden threats that would have otherwise been missed. To see examples of threats missed by unextracted scanning, view the table below where the original scan was marked as clean but the extracted scan revealed threats within the archive.

Customized Archive Handling Options
Metadefender Core offers customization options for the depth of archive scans, the maximum number of files extracted, and the size of extracted files. This gives administrators control over how archives are scanned to avoid risks associated with scanning larger files and performing deeper file extraction.
