We have a basic web page that allows to attach a file upload, eicar.txt is used in our case. This is posted as a multi-part.

Behaviour is consistent with different browsers: both Chrome and Edge show the same result. Both have javascript enabled in the settings.

There are no additional protections active on the VS: DoS protection and Bot defense are disabled.

The only violation that is showed is the 'Virus found'

Ok, got it. Several more questions to localize the problem:

  1. What version of BIG-IP do you use?
  2. What details are show for "Virus found" violation?
  3. Do you send it as regular post request or as AJAX request?
  4. Do you configure any Device ID functionality like Brute force, Session Awareness, Web Scrapping?

Thanks, Ivan
