sounds to me like you have had your DNS settings hijacked.
UPDATE: I just did a WHOIS lookup -- the domain expired earlier today and was renewed. flush your DNS cache. If you don't know how -- google it
Or simply change your DNS settings to opendns servers. ( 208.67.222.222 & 208.67.220.220 )
download and run HitmanPro from surfright.nl
then download and run Malwarebytes (quick scan, not 'full' or 'custom') malwarebytes.org
EDIT: Of course, if your DNS is truly hijacked, you might not even make it to those sites...
YMMV
