One of the requirements for the upcoming public release of Officeshots.org is that all uploaded files are run through a virus scanner before they are made available. Picking a virus scanner for this job was easy: ClamAV. Finding a PHP library to interact with ClamAV proved harder though. The 3rd party library page for ClamAV points to two different libraries that provide PHP bindings for ClamAV but both appear to be dead and expunged from the internet. So, I created my own using the clamd TCP API, and because Officeshots is built using CakePHP I implemented it as a Cake plugin.
