Something keeps re-setting pop server setting in Netscape

[mariod]

My friend has a Dell PC with Win XP SP2 running Netscape 7.0 with e-mail capabilities.
After setting the POP server setting to its appropriate ISP mail server id, everything worked fine until he turned off the PC.
On turn on, the POP setting had changed to 127.0.0.1 and now he could not receive mail 'cause that setting is an internal port (right?).
He calls me up, I show him how to re-enter the correct server setting. All OK until turn off. Then scenario is repeated.
When we contacted the ISP, we were told that AntiVirus program we were running (McAfee's) was the culprit, that we should turn it off before accessing the e-mail program. Seems senseless to me since the AV is supposed to be on while e-mail downloads to prevent/catch suspect messages.
Any idea as to what causes this re-set?
Any ideas on fixing it permanently?
BTW, the SMTP setting stays fixed, no problem.
Thanks for your help. :dizzy:

Howdy:

Did it work when you disabled McAffee??

No we did not.As I said earlier, disabling an antivirus program that is supposed to check e-mail messages for virus content before activating/downloading mail does not make much sense. How else would you ensure clean e-mails?
I'll be seeing my friend next week so we will try it anyway...but....:confused:

Some av programs use their own proxy server to send your email through to check it.. McAffee and AVG are two that I know of for sure..

Nowadays, most ISP's are blocking proxy server use as a way to reduce spam.. ergo, they will not allow the email to come through the McAffee server..
