I'm in and have been in the same predicament for about 2 years now except the attacks, superuser hostile takeovers, redirects, call and message interceptions have been and currently are occurring on any and every device I had and still have. I can no longer access accounts I had since 2010. Google has my email accounts listing devices I have never had not, had any desire whosoever to obtain! I'm not an iPhone, iPad, Apple Watch-type of person…I love Android Everything. I no longer have a desktop not laptop, I only have my cellphone. Please, help.
Sorry to hear of your problems. Unfortunately, I'm not sure I have a handle on the issue.
What I think I understand from your post is as follows:
You have some issues for 2 years. What those issues are are unclear.
You cannot access some old accounts
You have never had an Apple device but Google things you have. I have no idea what that means.
You love your Android. I assume it's a phone.
You don't have any Windows operating device… but you have posted on a forum dealing with malware on Windows computers, probably because you don't know what else to do.
I suspect that I'm unlikely to be of much use to you, but if you could clearly explain the problem and what you are trying to accomplish, it may be that I can point you in the right direction for help.
