Links do not work - cannot enlarge images

Good morning,

 

I just bought a new computer a few weeks ago - Compaq running Windows 7 - and I use Yahoo mail.

 

All active links in my e-mails remain 'dead. That is, when I click on any link, the hand appears but it doesn't take me to the url.

 

When I tried to click on images on my eBay store, to enlarge the images, the image does not enlarge.

 

I am wondering if this has something to do with my Norton product. I renewed my Norton subscription on  12-31-10 and my old computer died on 1-4-11. Right now I am using the Norton that came with this new computer and wonder if this is causing the problem.

 

Your help is appreciated.

 

Thank you,

Fred
