I have a laptop with Vista and XP on it, apparently while on Vista, some popups came up saying we had spyware, and my brother dowwnloaded the software it offered.
Obviously this is spy/adware. I killed it on Vista and the internet is working.
On XP, NOD32, SpyBot and AdAware have cleaned it all up, but I have a strange internet problem. Google loads up, but if you search for anything, it slows down and displays a blank white page. eBay works fine, and a couple of other sites do, but Instructables and more sites including PCA don't.
