Malware scanners located at HTTP/HTTPS proxy level should be able to scan malware in any content 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.
