can't sign out of hotmail


New Email
When I log out of hotmail the log out process stops and 'hangs' at
I use Safari.
Steps I have taken so far: I have deleted all cache, cookies, history.
Problem occurs every time I click sign out since it first started happening May 8th, when MacProtector downloaded onto my computer. MacProtector launched when I clicked "Not Junk" in hotmail.
I successfully removed MacProtector Trojan horse, but still cannot sign out of hotmail. Changed hotmail password.
