It is indeed something, double check your account for any changes. The best way is to change password. If you can, try to stop blogging first. Observe for any changes, you can ask expert bloggers or computer experts on what to do on this situation. Have your desktop or laptop check for any viruses,spyware attack or anything that may cause this problem.
