What if they accessed the email, the private wallet keys
If OP deposits into
his staked address, he'll find out if it's compromised....
As far as I know, that works when you're banned, but not when your account is locked.
I still don't know how that hacker was able to breach my account.
The only safe assumption is that anything can be compromised now. Which means you'll have to wipe your computer, reinstall everything from scratch, change all your passwords, and restore your user data from backup.
While you're at it:
Don't reinstall your OS - switch to Linux. Mint is fairly close to Windows if you are not familiar with Linux.
