ive just had 8 failed login attempts on my fortnite instagram and 4 failed login attempts on my emails associated with my youtube channel

I've legit JUST seen other creators tweet out something similar happening to their socials

It seems that malware that was running rampant acouple months ago that got my youtube channel is STILL ACTIVE!!!

I fully factory reset my PC,  reinstalled my BIOS and reinstalled windows off a USB months ago and it evidently is still on my system somewhere so i have ZERO clue what to do....

(they didnt get anything of mine yet)
