At the moment it seems to be behaving itself, as these things do. However, this also happened to my mums computer at home and when Ad-Aware, Spybot and McAffee were run nothing came up. I rang up onetel to ask for help and they determined that there was a connection but that IE was not accessing the internet. They then pointed me towards the Microsoft support team, who were on holiday, and so I just ended up doing a system restore instead. I think I even tried a WinSockXP Fix but that didn't work. I think this also happened with my sisters laptop as well thinking about it! That ended up getting restored too!
