A while back I got hit by an info stealer, and I didn't know this sub existed at the time nor did I have the money to go to a dedicated shop in the big city (I live in the sticks), so I dealt with it on my own. But the steps I took are not the ones I see recommended around here, and tbh my personality is a bit paranoid to begin with, so given this was my first ever time being infected/hacked, I am still more than a bit shaken. Here are the details of what happened.
1) On september 5, I downloaded and ran the Ren'py info stealer. IN MY DEFENSE, the program I was actually trying to download was indeed a Ren'py visual novel, so that's why I didn't realize I had clicked the wrong download link until it was too late, I usually am a lot more careful about this stuff.
2) By the morning of september 6 I discovered my accounts were being stolen, although strangely (or maybe not so strangely, I do have a potential explanation) not all of them. My google mail, which at the time was the centerpiece of all my accounts, was gone, and so were my Nintendo account, my Reddit account and my EA account. There had been an attempt at accessing/password resetting my Steam account, but it had failed (presumably due to 2FA), and my Discord and Riot account had been left alone (presumably because I hadn't created them with my computer, but rather with my phone, and I was doing the thing where I would log in each time by using the phone app to scan the QR code on the PC).
3) I used my phone to change the passwords of all the compromised accounts, then I used the phone to straight-up create a brand new email address with a new provider (something I had been planning to do for a while anyway).
4) I reset my computer to factory settings, explicitly selecting the option to erase all data that had ever been saved on the computer. This is the part that makes me paranoid, because apparently according to many posts I have seen around this sub this might not be enough?
5) From the now blank computer, I reclaimed all the stolen accounts using the new passwords I had set up on phone, then I switched all those accounts to being associated with the new email address I had created on phone. I also made sure to have 2FA enabled on everything this time (and deleted the EA account altogether, honestly I couldn't even remember having that thing to begin with).
By september 7 this whole process was done, and all my accounts were supposedly back under my control. Since then, I have ran full scans with two different antivirus programs every single day, and they were all negative. I ran an offline scan (the one that checks for BIOS stuff), and it was clean. I made it a habit to check the list of connected devices to all my accounts in the morning when I wake up and in the evening before I go to sleep, and I haven't seen a singular trace of suspicious activity (the only devices connected are my computer and my phone). And most importantly, there was no blatantly illegal activity, such as my Reddit suddenly spamming porn bs (which, yes, it did do during the couple days it took me to resecure everything) or my Discord sending scam links to friends (again, my Discord appeared to have been left alone to begin with, although I did change its password and switch it to the new mail just in case).
It is now october 27, so it has been nearly two months since I picked up all these habits, and no suspicious activity of any kind has been spotted. So I *think* it's safe to assume I'm in the clear, but where I live we have a saying that goes "after he gets burnt the cat is afraid even of cold water". There will be a driver issue that will cause my computer to not immediately locate my wifi, and I'll be like "omg am I being hacked again?". There will be a delay in Discord voice chat due to server slowdowns, and I'll be like "omg am I being hacked again?". I am literally jumping at shadows, and the horror stories I read around this sub (resetting to factory settings without installing windows from ab external USB will not remove the backdoor! Info stealers can jump through your wifi and infect your other devices as well!) are certainly not helping.
So yeah, I guess this is less about technical help and more about mental help. Still, if you notice anything obviously wrong about the steps I took, please do let me know. And if there is any way to definitely check whether or not my device is actually clean, that would help too.
