For Online Computer Support, Ask a Computer Technician
Hello, it sounds like this pop up you received was a malicious file to hijack your email account and therefore reach out to other accounts you may have tied with your email, Google will never offer any "Corrective programs". I'd like to first start by running some security software on your machine... Could you please go to www.malwarebytes.org and download the free version of that?? Run a full scan and remove any infections it finds... THis is going to ensure you don't have what are called "Rootkits" that are monitoring your passwords and keystrokes for when we attempt to get your email account back.
