I'm looking for the best practices to ensure that a secondhand computer I plan to buy is as secure as possible. So far, I've thought of the following steps:
1. Disconnecting the BIOS battery for a while.
2. Wiping everything using a Linux live USB (or ideally a live CD for read-only access, if I had a CD drive).
3. Attempting to update the BIOS firmware to eliminate potential malware.
4. Removing the SSD and only using the HDD, since I'm concerned the SSD might not wipe everything properly and the MBR could remain.
5. Scanning everything from the live environment using tools like ClamAV.
6. Are there any additional suggestions for enhancing safety?
Any help and ideas would be greatly appreciated, thanks!

If you do all of the things you mentioned, you're almost completely safe! Wiping the drives generally takes care of most malware issues. My suggestion? Just stay calm and don’t stress too much about it.
