sleazebag; asshole; lowlife

That sleazebag lied again.

クズ is a common insult meaning 'scum' or 'trash', often used for worthless people. ゲス野郎 is more specifically about vulgar, sleazy behavior and carries a stronger tone of personal disgust.
野郎 alone is a rough, derogatory term for a man ('bastard', 'jerk'). ゲス野郎 intensifies it by adding ゲス (vulgar/low), making it a harsher insult.
Most common spelling; uses katakana for ゲス.
Kanji form using 下衆; less common but still seen.
Alternate kanji form; rare.
Compound of ゲス (vulgar, low, sleazy) and 野郎 (rough term for a man). ゲス is often written in katakana in this compound; its origin is uncertain but may be related to 下衆 (げす, 'low-class person').
