How to prevent avast from 【mis-killing】 our legal advertising code

I’m from a Chinese company named Emar, which is a legal Internet-advertising company, our platform gathers ad requests from a lot of websites and return our customer’s advertisement code. About one month before, one of our customers complained to us that our ad-codes are always intercepted by Avast on his computer.

We found it was a big problem until we realize there are so many PC in China installed Avast. So we’ve been trying to contact with Avast to ask for help for nearly a month. But until now, the problem is still not resolved.

Could anybody tell me why only our ad-code be intercepted and how we can avoid it ?

What do you mean by “intercepted”…? Post a screenshot.
