I want to scan and check for viruses.
May I ask why?
If you are running OS X 10.6.8 or above, you are fully protected agains all currently known malware that can impact it (and technically there are no OS X viruses).
If you are having issues, it would be more productive for you to start over with a new subject and explain what you are seeing so that others might be able to help you out.
