Hey everyone, I hope my English is okay since it's not my first language. Last week, I accidentally downloaded a suspicious .msi installer that messed up a lot of my Windows services. I mistakenly opted to keep my personal data during a reinstallation instead of erasing my disks entirely. The next day, I found my cryptocurrency wallet empty and got an email saying my Instagram account had been hacked. It seems like I might have had a keylogger or something similar. I ended up wiping all my disks and reinstalling everything from scratch. I also set up two-factor authentication and changed all my passwords. I've run several scans using Defender, both online and offline, but I'm worried about whether the keylogger is really gone. Is there any way to be sure I'm safe now? Thanks!

If you completely wiped your PC and reinstalled everything, then the malware should be gone. It's a good idea to also update your BIOS, though BIOS malware is pretty rare these days since there are protections against it. Just remember, doing a simple reset doesn't actually remove malware, so you're on the right path now.
You might want to verify the results of your antivirus scans. Glad to hear you used Windows Defender and MalwareBytes. If they didn't detect anything, that's a good sign. It's also smart that you retrieved your Instagram account and set up 2FA. Just keep monitoring your accounts for any unusual activity.
It's great that you did a secure wipe and reinstalled! Check if you have any network shares that might have been affected and see if anything was changed recently. Also, review your browser extensions, especially if they include password managers, since they could have been compromised. Make sure you change passwords for any accounts connected to services like Instagram, and check for active sessions to remove anything suspicious.
