What is the best way to go about getting rid of hackers that have gained access to all my personal computers, (both old and recently purchased) phones, and even random computers I use to simply get emails out to my clients?
(Ive attempted to Explain my story below)
My current solution involves using Deriks boot n nuke for my windows computers to wipe out all of my computers, installing the latest operating systems for my machines + phones then optimizing my network settings, setting up firewalls, and using a less vulnerable email provider for my business.
I began to become suspicious when some of my clients started complaining that they weren't receiving my emails from my business account with AOL. When I had a computer repair place check out my main mac computer they found a large amount of startup programs that were scanning me from multiple sources watching my computer activity. He claimed to have fixed it but it seemed things got worse This continued with all of my other business computers, even new ones I got ahold of, After apples Genius' weren't able to figure out what was going wrong or how to fix it. I've starting to just try to find out ways to fix this on my own. Any suggestions on solutions that will work?? I'm relatively new to any sort of hacking.
