Can't Load Certain Sites Over Lan

[AcID ZeR0]

I can't load certain websites on my laptop or other pc but i can load them fine on the pc examples of these sites are (windows update, ebay, norton etc..)
I'm pretty sure it's a virus but none of my programs can detect it any idea what I should look out for?

I already tried them it found a virus eailer which came in from a pc on my LAN but since then I can't access sites like ebay, micosoft etc.. the site that only really works 100% is google.
This has really puzzled me because I've never had something like this :frusty:
