Norton 360 frozen

hello, My norton 360 seems to be frozen on the full scan. Its been over 3 hours since I've ran the program. the security log shows the scan took an hour and 3 seconds, but its still scanning. what should I do?

 

also I had a WS.Trojan.H exonerated in my security log files, which is why I ran a full scan, but the log is missing now. Is there a connection?
