Problems Jooma Firefox & Kaspersky: 200 Request has been forbidden by antivirus

Question

I am using Joomla 3.4 with Firefox and Kaspersky Internet Security. I am receiving the error

200 Request has been forbidden by antivirus 

all the time until the buffer is full and Firefox hangs. It happens on my own site and others For example http://forum.joomla.org

If I exit Kasperky that message disappears but is replaced by a JSON syntax error in what looks to be a temporary generated file. Has anyone else hit this? I have had no solution offered by Kaspersky nor (so for) from joomla.org.

Regards Nick

Answer 1

I had a similar problem with Kaspersky and Firefox when working on a web development project. (C# ASP not Joomla).

I disabled the Kaspersky add-on for Firefox and disabled "Web Anti-Virus" in Kaspersky.

To disable web anti-virus go to Settings -> Protection and then slide "Web Anti-Virus" off.

I did some extra research: This can also be a result of the "Anti-Banner" feature that can also be disabled under Settings -> Protection.
