Andy, I would steer clear of anything that is highly tactical in nature. From what I understand, even at the very highest levels of human competition, open lines are deadly.
Bad chess openings accorording to computers

there are some openings that aren't bad but computers tend to steer clear of. for example i've never seen an engine recommend the Scandinavian defence.

The Dutch Defense is a prime example. Computers dislike it a lot for black, but over the board it create a lot of complications, and gives GMs the ability to win games in those complications.

Engines does not like or dislike any openings or variations. They rely on statistics. Deep Fritz cannot defeat Stockfish defending the Dutch defense or Alekhine. The starting position must be set up manuallly as Stockfish will never choose the Dutch or Alekhine as engines rely on statistics.

I'm sure it would all depend on how many centipawns you consider the engine to think is an unacceptable loss.
for example. surely 1.Na3 or 1.Nh3 are some of the worst moves in the games and those would be some simply dreadful places to place a knight. but how many Centipawns COULD an engine dock white; when the move doesn't give away a pawn and white had initiative anyway?

Are there bad chess openings against the computers? I mean does it exists openings that are OK according to humans, but bad according o computers?
It's interesting to go on something like Lucas Chess, play a game against yourself, but ask Stockfish 8 to evaluate the moves. The openings computers like Stockfish finds awful are generally the ones humans find awful because they don't fight for one or more of space, center control, tempo. and aggression.
For example, the "Crab Opening," which people tried in the '70's and everyone thought stupid then, begins 1 a4 e5 2 h4 and Stockfish 8 (20 ply) says White is behind 1.05 pawn equivalents already.
Stockfish only finds the following moves to be favorable for White on the first move:
1 d4 +0.33
1 e4 +0.31
1 Nf3 + 0.18 (Reti was right!)
1 e3 +0.15
1 Nc3 +0.01
1 d3 doesn't even make the list of top 15 first moves!
Of course, Black's first response can potentially push the number toward Black or in Black's favor.
Note, by the way, that the top computers play better when given a database of accepted human known openings to use.

My computer always e4 for white and french defence or open game for black
Try the free Lucas Chess (http://www-lucaschess.rhcloud.com/index.html).
It uses a lot of different engines and allows an incredibly wide range of ratings (200-3300) and playing styles (reckless, solid, etc.), how random and good you want the engine to pick occasional non-best moves, or have it play at the level you appear to be playing - or better or worse, and if you want to work on certain openings you can dictate as many or few opening moves as you'd like. That results in a lot of varied play.

Yeah, it is a pretty good song. I am still wondering why in the world would an almost 2000 FIDE ask such a question.

Agree it's best to stay away from tactics in general with computers. I've had good luck with the London, Catalan and Larsen openings. Trading queens early usually helps.

The question is completely serious. Do yoy have anything other than insulting to add?

Yes. Openings were you give material to get dynamic compensation (gambits) are not the best openings to play against Computers. They will neutralize your counter-play and you will end up with less material.
Now, I will keep singing.

What opening moves do computers without an opening book like best, based solely on their own analysis? Which do they like the least?

Engines hate on the KID because of their (not including neural engines) obsession with space and material. At times they give +3 when White is getting mated.
