Looks like either scale or aphids- the photo is too fuzzy to tell. Either way, it needs attention! Check the other plants- chances are they are affected too.
I still can't tell, but if the plant is small enough try wrapping a plastic bag around the pot of soil, and dip the whole foliage in some soapy water. Basil is tender and you will probably break it- if it were me I would take some tip cuttings that I was sure was clean, and destroy the rest of the plant. Unless it has special value to you, seeds are very easy to start.
Google "scale on plants" and see if anything looks familiar.
You're welcome- and I agree with you about DG- I have learned so much, and sometimes I am able to share my experiences and help others. We never know it all!
