Negative energy, bad vibes.

Hey y'all. I feel like I'm very intuitive, and usually my gut is always right. What are some practices, or things you do when there is someone around you who just gives you bad vibes? I have a about 2 people in my life who whenever they are around me, they just give me a feeling I can't explain. Like I can literally feel that their intentions aren't good or they have ulterior motives, and I know they don't have my best interest at heart. Please help!
