Active or passive mode ?

Hello,

I use Nod32 v3.0.669 french under windows xp home sp3.
I have a question about a setting. My browser is Firefox 3. It is about : http -> browsers -> Active mode. When I want Firefox.exe to be scanned in active mode, some web pages look like this :

Server: Apache/2
Set-Cookie: bblastactivity=0; expires=Tue, 08 Dec 2009 18:22:47 GMT; path=/; domain=.wilderssecurity.com
Expires: 0
Cache-Control: private, post-check=0, pre-check=0, max-age=0
Pragma: no-cache
Set-Cookie: bbforum_view=a7b1f30fc0a064510773be059fe6dca2a-2-%7Bi-15_i-1228760561_i-88_i-1228760567_%7D; path=/; domain=.wilderssecurity.com
Vary: Accept-Encoding
Keep-Alive: timeout=5, max=200
Content-Type: text/html; charset=ISO-8859-1
Transfer-encoding: chunked
ETC ... etc ...

I won't paste the whole page
Can you explain this strange behaviour ?
In passive mode, unchecked, everything is fine. In fact, I had in mind to have maximum efficiency for porn sites.

Thank you.

 

You'd better not visit unknown and risky sites such as porn web sites . Of course , there might be some legitimate paid one which generally will pose no risk but there are quite a lot that are risky.

Anyway , you asked about explanation ... Here is one , part from it taken from NOD32's v2 help file and modified for v3

I use passive mode only .
