Why can't I read the emails on my ymail account?

I cant read emails from my yahoo and norton 360 wont allow access to anything with a password.?

• i have a dell computer with vista home premium on it. When the 30days free mcafee ran out, i stopped being able to read the text on my emails or compose and delete them on my yahoo account. i have tried the encoding and erasing of cookie history etc. This doesnt work. I now have Norton 360 protection as i couldnt successfully load on mcafee again and this doesnt like me accessing anything with passwords (inc my norton account), can anyone help. its driving me nuts!!!!!!

• Answer:

  It sounds like Norton 360 is on high alert and doesn't like any sort of internet activity. Personally, I can't recommend any particular settings for Norton; however, will recommend that you don't spend money on Norton again. There are a few free anti-virus applications on the net that do just as good (if not, better) job than Norton. Including Avast and AVG. Try un-installing Norton and using the net. If it works fine, give Avast a go. Download and install it and take Norton back to the store if you're quite happy with Avast (and your internet's working fine). http://ma.gnolia.com/gazushav
