Dev-Info: To protect our hundreds of millions of users, we disabled the emulator. The disablement of the emulator won't affect the functionality of our AV product, which is based on multiple security layers.
Yes. If that sentence, which I've read, contains the answer to my question -- I missed it.
My reading of it is, if the emulator has been disabled (it won't be run), then so too would be the potential problem. That would give time to either fix the bug or do it another way.
You were considering disabling web shield scanning as a means of mitigation, a sledge hammer to crack a nut, the disabling of the emulator, is using a smaller hammer and allowing other functions/levels of protection to also run.
