Is it possible to get a virus on a MacBook Pro

It's extremely unlikely. Since you haven't given any description of why you think you may have a virus, I can do know better than to refer you to this excellent site:

, which describes the main types of malware (uncommon) and adware (very common) that plague Mac users.

No one can detect such stuff from OUTSIDE your Mac.

Web sites that claim you are infected with anything are always a SCAM.

It's best to describe the problem in as much relevant detail as possible, rather than what you think is causing it or how you think it should be solved.
