XP OE pop3 ?

Hi !
I'm having a problem with OE keeping the pop3 server address,
I set it up right and it works fine, but if I close OE and open it again it changes the pop3 to "localhost ", then takes the right pop3 and adds it to the end of my account name with a "/" after my account name. when it does that I can get mail, and when I send it, no one gets it.

I had this computer hooked up to my network, cable connection with router, now it's by itself with a dial up connection.

 

I never would have thought that, ...Ok.
I can get mail, but I can not send it, well I can send it, it goes to my Sent folder, but it doesn't reach it's destination, don't know where it goes.
I'm using PC-Cillin 2000.

 

You are right! it is pc-cillin anti virus. They have a fix on web site, that should work.
