Maybe you have a look at the McAfee Help forum:
I recently installed Mcafee VirusScan. It won't update the virus list. It gives a " page cannot be displayed" and then says it found a earlier version of winsock2 and needs a updated version. It gives a button to take me to a windows 95 page from microsoft to download a winsock2. I have win xp home and don't think I should download a 10 yr old update?
Also, VirusScan now won't let my outlook express work. No email send/receive. I deselected the email and spam scans but it still won't let Outlook work.
