We have a MacBook Pro and an IPad. A couple people from my wife's email contacts have reported getting emails from her that she didn't send. She uses the IPad for her email 95% of the time. Occasionally shell use the MacBook Pro. Is this a problem that could be coming from the IPad or is it the computer? I'm currently downloading and running Clamx and iantivirus on the computer. How do I check the IPad if I need to?
