Can you help me identify this spider?

This is the second spider of this kind that I have killed in two days. Here is a picture of the home intruder’s face. I’ve never seen anything like it before. It has a bright red lower body, its legs are patterned as you can see in the photo and it’s a wittle bit hairy. I did Google some photos, but I’m still unsure so if there’s anyone who can help, I’d appreciate it. What the hell is it and should I be concerned?
