Yes, own JavaScript Code.
It is related to the Discussion Post: #11407 (reply in thread)
No own extensions, only JavaScript Code from Code Base and the Code you can see in the <script> part.
It covers doxygen, yes.
Because my Anti-Virus Application is upto date.
And always I open Documents like E-Mails, or HTML Sites, or always all Files will be forensic Check before I can make changes.

In other ways, when I try to use the JavaCode like you can see it in the Post above, I get the following Screen-Attempt:

Either my Code is incorrect, or the Code Base from doxygen is not anymore comform.
I try to download, and compile, and test the current Version and I will inform you.

But I was thinking, that you have the informations that JavaScript is eventually hi-jacked - or a problem with HH.EXE.
