Hi,
Last day I was trying to test an older version of maldet. To be precise V 1.4.0. I spent a lot of time searching for the source file without any success.
Every link I lookde gave me only the following link to download.
wget http://www.rfxn.com/downloads/maldetect-current.tar.gz
Then I tried a work around. Replace the 'current' in the download link with the correct version.
wget http://www.rfxn.com/downloads/maldetect-1.4.0.tar.gz
Tadaa... It worked
Hope this will be helpful
