...before receiving an error message about checking web settings
Please give us the exact text of the error message; the more specifics we have, the faster we'll be able to help you.
Is this correct going via av.rds.yahoo.com??
Possibly; av.rds.yahoo.com is a valid Yahoo address, so it may or may not be part of your problem. Again, some specifics will help:
- Give us the URLs of some of the sites that exhibit the problem.
- Do you have anything Yahoo-related in your browser setup (the Yahoo tool bar, using Yahoo as your home page, etc.), or does your Internet Service Provider have some sort of affiliation with Yahoo?
