I’m working on a website that supports user-uploaded files. I want to virus scan these files before any file processing or making them available to website visitors. Is there a COM/ActiveX programming interface available to developers for Avast Server Edition?
I should be able to write the code using the command line interface and scheduled batch processes but that’s a bit clunkier than COM. I thought I would ask before I head down that path.
No, I’m afraid no such interface is available.
You can become an OEM partner though - and use the engine directly on DLL level 
Since this is for a single site I don’t think there’s much value to Alwil in me becoming an OEM partner. (It sounds expensive too. We won’t be reselling anything. This is purely for use within a few websites that handle user submitted files. I have a working proof of concept at the moment using the command line scanner as a wsh.exec process. It works but I’ll need to stress test it to see how many files it can handle per minute under load. Launching an out-of-process task is quite expensive in terms of processor cycles.
Just out of curiosity, what’s involved in becomming an OEM partner.
BTW, I decided to use Avast in my application because I am a SurgeMail customer and I am very happy with the OEM implementation of Avast in SurgeMail.
Honestly I don’t know (what’s involved)… I guess the licensing is individual.
But yes, it’s meant for somebody selling their own product with antivirus scanning capabilities.
