what is the love described in Buddhism?

I heard from Buddhist monks love is "kamachannda" and definitly a "Klesha"(hindrance).When I analyze the definition of love in in Oxford Dictionary it states; 1. An intense feeling of deep affection(a feeling of fondness or liking.) 2.A strong feeling of affection and sexual attraction for someone. So this is a match with "channda"(liking) logically no body love something or some one which dislike. Once I search single word for "metta" in English; Universal love (as mention in "What's the Buddha thought by Ven.Walpola Tero) and this is the common interpretation for "metta". So is loving wrong thing to do?what is the difference of love and metta? Is love an attachment?
