You didn't mention what type of paint, so here's an article with methods for different paint types. I hope this helps you. Wishing you the best.
Scrap and wash down with Denatured alcohol. May need a soft plastic bristle brush if it is textured.
We got some drops of paint on our vinyl siding and my husband used acetone to remove it. You can get it at home improvement stores.
If it is not to heavy try just scraping it off with your fingernail. Normally since it is vinyl it wont sink in, What ever you use try a small spot to make sure it doesn't effect the color and try it on a small out of the way spot before you get carried away
