Hi Clouise,
Sounds like Euonymus scale aka Euonymus alatus scale.* You can read about it here.

There is a clickable link to this page, but I would never use most of the toxic chemicals they recommend.*

They do recommend insecticidal soap and horticultural oils, both of which would be a good option.* If you use a horticultural oil I would recommend one such as Organocide, which is made from sesame seed oil and NOT Organicide which is made from petroleum.

When weeding, the best way to make sure you are removing a weed and not a valuable plant is to pull on it. If it comes out of the ground easily, it is a valuable plant.
