I try not to scare too easily over this stuff, but I guess you have to heed these warnings.
I've only bought unsalted, unshelled peanuts for the birds, like them but usually don't buy too much of that for myself. I love peanut butter on bananas, and lately when I don't have much to snack on, I eat a couple spoonfuls of pb.
I don't think you have anything to worry about. A lot of what is being recalled is probably safe enough. Wouldn't baked peanut butter cookies have the virus destroyed by the heat?
Also, maybe it isn't heated high enough, but it appears pb in jars has been heated so it can be poured into those jars by machines.
The store bought PB cookies are probably a room temp paste, dehydrated then flash browned, not actually cooked the way homemade would be. Such formulating twchnique will not kill the bacteria inside the paste but would reduce number in a cookie until it had time to flourish on the shelf.
