Translation of "Malicious" in Japanese

Beware of 'One Ring' malicious nuisance calls!!

悪質な迷惑電話、ワンギリにご注意！！

Malicious gossip spreads like wildfire. I guess that's why they say bad news travels fast.

悪事千里を走るって言うだろう。悪い噂はアッという間に広まっちゃうのさ。

Even if malicious gossip is being circulated around someone, it doesn't necessarily mean that the value of that person will be diminished.

悪口雑言をいわれても、いわれた人の価値が下がるわけではない。

There are frequent instances of malicious door-to-door selling, such as pushing water purifiers on people after carrying out water quality tests without permission.
