I need help to get out of this system

[FelipeAceved0]

I speak Spanish so I use google translator I apologize for any grammatical errors.
a while ago on September 16th or so a virus entered my accounts and that changed passwords I formatted the pc and changed everything to be safe but today October 7th I get 3 emails to steam at 6 in the morning that I gave gifts to an account that I don't know but that was in the group of this system, I got scared and deleted everything, I left the group, changed the password and deleted the devices connected to the steam account but I'm afraid that when they hacked things they entered my steam account into this without me knowing so I would like to know how to delete my account from this since I saw that I have cards and several games were played on October 2nd help please

Hello Sir,
Ensure nobody else have your credentials so they cannot use this software or any other on your behalf.
You might want to ensure that you reset your password and 2fa as well as revoke any apikey / web token on your account.

Cheers

Ok, thank you very much indeed.

For future use I will leave this here:

• API-Key revocation
• Signing out all sessions (red button at the very bottom)

Additionally, I recommend you set up SteamGuard two-factor authorization if you haven't already.

A strange useful trick that I heard once and still use to this day, is have family view activated. Is just a simple 4 digit pin, but you can configure it to essentially have your whole steam ecosystem in lockdown unless you unlock with the pin.
They can't navigate store, access inventory, edit settings, even send messages to your friends tricking them.

Just FYI - family view code can be cracked in a matter of minutes(and that's in the worst case, if PC is very old, on new PC it's a matter of seconds).

ASF even has built-in functionality for this.
