I keep getting redirected to Gateway google search page.

[tranklam]

I work/play at ebay a lot. All of a sudden whenever I am there I keep getting redirected to a Gateway Google search page saying: sorry we couldn't find http://us.ebayobjects.com/1ai/ebay.us.myebaysellingsummary;dcopt..........with web search results listed. This happens ALL THE TIME. I am unable to get anything accomplished. I know nothing technical about computers + my computer is brand new. I deleted my favorites link taking me right to ebay, deleted cookies/browser history & have tried accessing ebay through typing it in to the browser and I keep getting redirected. I have Trend Micro Antivirus & Webroot spy sweeper, preformed scans on both, found nothing odd. I don't know what to do? Any help would be greatly appreciated! Thank you
P.S. I'm sure I don't even have this question posted in the correct catagory. If it should be elsewhere please let me know.
