Suddenly about 2 weeks ago I began receiving responses from websites when I would login. I would get an email saying that my password was used from a new device and if this was me not to worry but if it wasn't me to change my password contact them. I've had the same Samsung Galaxy 7s for 5 or 6 years and it is my only internet access. Is there some weird kind of worm that would cause this? It's happening on Amazon and PayPal and a whole bunch of other website so I don't think it's their issue but I have Webroot on my phone so I don't see how it could be mine. Can somebody tell me what's happening?
