Ok I am getting slowly to the clue of the problem I hope. When installed EAV v4 alone FF is running fine, and on the speedtest the ping is around 11-15 . When installing a firewall like PC Tools or OA or Comodo the speedtest says the ping is around 500 or more. When removing EAV v4 everything works great. When using any other anti-virus incl. EAV v3 no problems. On IE8 all works fine too. I could use it but prefer my Mozilla . Maybe I should change some setting in Mozilla. I just can't imagine I am the only one who is experiencing this problem? I thought it was my PC but I am slowly finding out where it could be but I am not technical enough to fix it I guess.
