DAN landing pages blocked by antivirus, firefox

Hi,

I had this problem in the past, but now it has occured again.

And I think even a bit worse.

While in the past, only my browser (firefox) did not forwarded to DANs landing page,
while telling me there is a risk to go there,
and explicitly asked me if I want to continue (which I did -- but what end-user would do it..?),

now my antivirus software does the same!

Its now 2 fold:

First my antivirus says
"A suspicious site has been blocked for your protection"

after I choose to go forward,
firefox does the same, and I have to agree on it again click "accept risk", ...

What the hell is happening here?

As I had it with firefox in the past, I contacted DAN support, they looked into it and said there is no problem etc.

And it was, that new pages weren't right away visitable with Firefox, and you got that "risk alert" beforehand,

and after a while that page (domain) had been online, it went away...

(or it went away as I had visited the site before as well... ?)

Now the problem is worse, as both, antivirus and browser, doing this.
