Transfer Encodings

Malware scanners located at HTTP/HTTPS proxy level should be able to scan malware in any transfer encoding that web server and browser may use.

Test these links with your HTTP/HTTPS proxy malware scanner. Every malware scanner is able to find the EICAR test string. Should your scanner fail with some of the formats, the retrieved test file will not do any harm to your computer. When executed, it simply displays a test string. More information on the EICAR.org web page.

The EICAR.com file with chunked transfer encoding. This encoding must be supported by all HTTP version 1.1 agents. If the request is of HTTP version 1.0, you will see a notification where you can decide to try this encoding anyway in order to test your scanner. Data transferred in chunked encoding will be sent in three chunks.
