I opened a suspicious gmail attachment in my iphone, ipad, and laptop. Unfortunately, I downloaded the attachment in google doc format in google drive. I changed my password immediately after realizing it wasn't from my colleague. I’m worried if my devices and google drive are now exposed to hackers. As of now, they seem to be unaffected with no issues using the devices or drive. Do I need to reformat all my devices to be safe?
