If it's externally hosted, then its definately safe since it's not on your network. Depending on your experience, you may or may not want to host it yourself.
I've never hosted with Lycos, but others have. So long as they provide mySQL, PHP and other typical hosting options (preferably Linux over IIS) I would assume your good to go there. Check with others here about their experiences with Lycos.
Good Luck
