Found BC via Google search " Browser Air removal". DLd AdW cleaner and ran. AdW Cleaner is a life saver. Ive been using Malwarebytes and SuperAntispyware. Both detected and removed BA,and others but didnt "deep dive" like Adw Cleaner so Browser Air and others kept popping up after each new boot. Now 100% cleaned even the "invisible" malware files gone. Thanks very much AdW Cleaner and Bleeping Computers.
