user10967: 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;

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? 

user254: 'Love' is an imprecise word in English. It's used in the phrase "brotherly love", for example, which may be more or less like metta; and used in other phrases like "motherly love", "love of chocolate", "love of country", "self love", "making love", and so on, all with different meanings (depending on who is loving, what they're loving, and how).
So even in non-Buddhist (e.g. Christian and/or European) philosophy, for example, some people tried to standardise on using and understanding different words for different kinds of love, for example:

Philia (/ˈfɪljə/ or /ˈfɪliə/; Ancient Greek: φιλία), often translated "brotherly love", is one of the four ancient Greek words for love: philia, storge, agape and eros.

... sometimes using non-English words in theological or philosophical treatises.
It's difficult or imprecise to translate Buddhist terminology, from a language like Pali, into a language like English whose (English) words have different (non-Buddhist) common ("vulgar") cultural meanings.
It's necessary to do so (necessary to try to translate) for the sake of those who only understand English.
But if you're asking, it may be more precise, more accurate, to ask about and learn to understand the meanings of some of the key original Pali words ... like metta, like chanda, and so on.
Chanda (desire) in Buddhism isn't necessarily bad ... the desire to be good (virtuous), for example, is maybe a good (virtuous) desire ... but kāma means something like "sensual pleasure" (kāma is not the same word as kamma) ... so kāma-chanda means something like "desire for sensual pleasure" (and it is defined as one of the fetters).
Conversely, metta is one of the four brahmaviharas (which I asked about most recently in this topic, see also other topics tagged metta).
In classical Buddhism the "wrong thing to do" is more-or-less defined by the "four noble truths" ... which I think say that you experience suffering and/or dissatisfaction (Dukkha) when you "crave" things (that's Taṇhā, a different kind of desire, always 'bad') and "attach" to things (Upādāna ) ... and/or "wrong thing to do" is defined by not keeping (at a minimum) the five precepts.

user43: You know that feeling when you like/love something or someone so much that you feel the pull, you want to have it, you have this sense of string attached to your stomach pulling you to the object you're fond of?
That's what the word "kama" stands for. It's the pulling aspect of love, the "I like what you're doing to me and therefore I want you".
Metta/Maytri has a different meaning. You know, when you are in love with someone, you like everything about them: the way they look, walk, talk, eat - anything. And even their bad habits and mistakes look cute, because you accept the complete person, it is absolute 100% unconditional acceptance. So the word metta stands for this kind of acceptance or tolerance, when you take the person as he or she is, without judgement, without shame for them, you just take them exactly as they are.
So in Buddhism this desire to have someone ("love") is recognized as a problem. While unconditional acceptance ("love") of everyone, including oneself, is a virtue to be cultivated.
