Recently my computer got infected with a virus, which encrypted all my files with a .zzla extension and demanded a payment to get them back. Since all my valuable data was backed up, i decided that i would just reset windows entirely and it would kill the virus.
I reset it from the settings, and selected the option to delete everything on the drives. After that, it seemed as if it worked, windows appeared to be normal, but windows security started acting really strange, turning off and on again, sending weird messages for programs which shouldn't be malicious(anvir task manager, gridin anti malware).
And then - I get a ton of notifications from Discord - someone(or some virus) had sent a ton of fake phishing links to everyone on my friends list, and some random people. I deleted the messages and logged out, and I created a Windows Media Creation Tool, so I could start a completely new installation of Windows on a formatted drive.
I formatted both my drives and the partitions, and again it seemed to be normal at first, but last night the same thing with Discord happened, but this time on Instagram - it posted on my account, my story and followed random people. I checked and saw that there was a log in from Helsinki, and I don't know how that's possible since I have two factor authentication turned on.
But my guess is that since I was logged in Instagram on my PC, this hidden virus logged in from my browser and that's why it wasn't detected as a new log in.
Mind you that this happened while I was asleep, and the PC was turned off. I don't know what to do, please if anyone has any idea what I can do, I would love some help.
Windows Security doesn't detect anything, neither does Malwarebytes, Gridin antivirus, or Bitdefender. Would buying new drives and throwing away these help? Or can this thing attach itself on to the BIOS or something like that?
