I've used all of the above to control Euonymus scale. For Malathion and Sevin, sprays should begin when the crawlers are out and then repeated every 7 to 10 days for a couple of sprays. You could use a product containing imidacloprid or Safari. Many forms of those are root drench or applied to the soil. It's slower to work than a spray, but will last a lot longer inside the plant. In bad infestations, the plants can be cut back to the ground and treated when growth comes back out.

Stompede, Thank you.
I sprayed today with Orthene this morning and I'll repeat it every 2 weeks...hopefully that will do the trick.
