ClamAV

Please refer to this link for the latest list.

CSS Premium

This engine has standard unpacking methods for the most popular file types, but will scan files byte-for-byte if the file is not "natively supported".

Data Classification for Amazon S3

Our data classification functionality supports scanning and classification of most text-based files. This includes the following:

• TXT
• DOC/DOCX
• PDF
• HTML
• CSV
• XLS/XLSX
• XML
• RTF
• ODT
• PPT/PPTX

Even if a file type is not on this list you can still upload it and attempt to classify it to see if it's supported.

Support for Archive Files

Our scanning engines support scanning files nested within archive files. The maximum supported archive depth depends on the scanning engine.

Supported Archive Depth

• Sophos: Up to 5 levels of nested archives
• ClamAV (CSS Secure): Up to 10 levels of nested archives
• Bitdefender (CSS Premium): Up to 16 levels of nested archives

If a malicious file is detected within a nested archive, the entire parent archive is marked as infected and moved to the quarantine bucket.

For Sophos, the scan result and object tags include a message identifying the file within the archive that was detected as malicious. For example, I uploaded a four-level nested archive containing an EICAR test file at level 3, and the scan result identified the infected file.

Bitdefender (CSS Premium) behaves similarly. The scan result includes a message identifying the infected file within the archive.

However, CSS Secure (ClamAV) cannot provide the same level of detail as Sophos or Bitdefender. In the Message section, the message will be empty, and the entire archive will be marked as infected. You will need to inspect the archive to determine which file within it is infected.
