I think all banks have equally secure systems. But for sure you should consolidate your accounts with a major bank that has an office in your area. Then you should get online access to your account and check it weekly! Use a new log-in and password for this new account.
Then, read this and FREEZE your credit report after you open the new account.
And then, I hope you have a secure connection on your computer to the Internet. If you have a teenager — child or grandchild — ask them to make sure your computer and internet access are secure.
That should solve your problems for the future!
