Thanks for the tips everybody!
I just checked the hosts table and all that's there is my local host.
I ran spybot s&d and it did detect and get rid of stuff, but the problems are still apparent.
Here are my results after pinging certain sites:
www.tfproject.org/tfp - "Ping request could not find host..."
www.tfproject.org - "Ping request could not find host..."
mail.yahoo.com - First ping timed out. Second try had 25% loss.
www.yahoo.com - 0% loss.
www.google.com - 0% loss.
www.nba.com - 0% loss.
www.gamefaqs.com - 0% loss.
www.fark.com - 0% loss.
www.hobbyinsider.net - "Ping request could not find host..."
www.beckett.com - "Ping request could not find host..."
Any idea on what's farking up?
