My Dad recently passed away and Mom is already looking on single sites

My Dad recently passed away after having a massive stroke on August. It's been about 3 weeks and I have started hearing my Mom tell her friends that she has a lot to love to give and will start dating again. Although in the end I want her to be happy and not have to be alone, but I am so worried that someone will take advantage of her and take my Dads hard earned money. Not to mention its soo soon and kind of hurtful hearing her say these things. I don't know how to talk to her about this. I know she is still grieving but I'm just so worried. This is the perfect situation for a scammer to come in and take advantage of her. She is way too trusting and will let people walk all over her. Is this normal for someone to start thinking of this already?
