w shows who's got past your defences and actually logged in. So
"suspicious" is worrying.

Is there any chance that it could be legitimate -- say, someone you know
SSHing in from an unusual IP address?

Can you run
host 10.10.10.10
(where 10.10.10.10 is the IP address) to see if there's a name
associated with it, and
whois 10.10.10.10
to see who "owns" that IP block?

Unless you can verify that whoever it was had permission to be on your
computer, you should worry, try to find out how they got in (are any of
your passwords guessable? How many usernames are allowed to SSH in? Are
you running any other server programs?) *re-install your system from
scratch*, and do your best to close the holes.

If you want any further explanation, please ask this list.

Thanks,

James.
