why is this happening?

i use mozilla firefox and when i go back to the home page,not all the time but some times another smaller page opens up it doesn't seem to load properly and the name of the page is "readmeadia.247realmedia.com" i am a complete idiot when it comes to computers(can switch it on and print things)so if anyone has any idea what i am on about could they let me know if i have a problem.thanks i forgot to say i scan the computer daily for viruses and it is all clear

When you say 'Home page' do you mean:

http://www.dogweb.co.uk/talkdogs/
or
http://www.dogweb.co.uk/

oh sorry my homepage is ntl and it is like this
http://www.ntlworld.com/
as i say i am really thick when it comes to computers it is probably something i have clicked when i shouldn't have

It's probably just one of those randomly rolling adverts that come from time to time. You probably haven't got a Real media player installed so it stalls.

Nothing to worry about ....

thanks royv i am sooo paranoid about viruses and hacking

That's good. You can never be too cautious in this day and age ...

Yes Roy is right Sounds like one of the adverts use 'real player' its a multimedia player that lets your browser show 'animations'...
