Squidguard

We have installed squidguard on our linux computer.

Now when I go to pick up mail from lycos.com I get the following error.
(I'm using xp and windows explorer.)

If this is wrong, contact

Can anyone tell me what it is blocking and where to change this type of
thing that it is blocking. There are alot of config files and IM not
sure which one to use or where it really is.

Thanks.
