Got hacked, recovered my account. Problably a trojan got into my secondary PC. Now what should i do to make the hacker don't enter again?
Today i got a message from instagram on whatsapp for a code that i didn't request, after i logged into instagram, i got logged out, password changed, and email change to this email: "rdokj9133@neegax.com", but the hacker didn't change my phone number, and he forgot to remove my verification selfie, with that i was able to retrieve the account and kick the guy out. Next was my Discord, it got hacked in the sameway, but i got into it quick and changed the password. After was my facebook, the samething as instagram. Yesterday was my primary Google Account, google helped me getting it back, same thing for my microsoft account. The guy is still trying to get in, as i'm getting emails of failed login attempts by google. 3 emails got leaked and password leaked, which where, my primary google account, my secondary and my School Google account, for the school account, it was easy, they don't let anyone outside of my country log into it, and change passwords, so i just changed the password of it, my secondary was almost acessed, but i changed quickly the password, same as my main one.
One of my emails that didn't get leaked was my iCloud Email, i changed all of my passwords and emails to it, as i didn't get its password and email leaked, and its not that easy to hack it, as i have 3 iphones which to login one as to allow the login and i have to type an code to enter. For the google account, Microsoft Acccount, Instagram, Facebook and Discord account, the guy bypassed somehow the 2FA, not to worry as i changed the email and password, so it wont be easy for him to enter now.
And what this means, one of my computers, my secondary one, used by my family, problably got a Trojan and stole everything, and it seems the trojan hid himself in the regedit to exclude him from being detected by Windows Defender, now, i don't see any strange processes in the machine. First of all, I DON'T WANNA LOSE MY DATA from that PC, as it has lots of informations and programs that my family uses, and resetting it, would bring much trouble and problems to me. So i need to find a way to verify if the virus is still there, how to remove it, and make the final verification to see if it got removed and its safe to use the PC.
Also i want to know if bypassing the 2FA is possible (and how it was problably done for me to all my accounts with 2FA being bypassed). My primary PC is cleaned i checked everything and its cleaned. I have so much accounts that i use and need to change it to my iCloud Email, just to be safe.
So what i do now?
