Quick fixes for hex removal (and no, they are not that creepy)
Always keep a black candle lit in your home, prefferably a reversible
Keep a medallion / talisman on always (neclace, bracelet, ring any jewelry with a natural stone). Don't let anyone choose this piece of jewelry for you, you should choose whichever "calls" to you.
In your mopping water, sprinkle a little bit of cayenne pepper (about 1 tsp) mop as usual
Burn garlic peel whenever you clean
keep your house tidy, for some reason malicious energy is drawn to cluttered / dirty areas
To recommend a spell I'd have to know what the exact source of negativity is.
Hope this helps!
