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.
