How safe is my pc?
A few days back my computer got infected with a Trojan. It triggered a blue screen warning about an unmountable volume and caused repeated loops. After resetting it and wiping everything, I still don’t see any signs of the malware. Even my antivirus reports I’m safe. Are you really sure?
Your system is secure as long as the reset occurred prior to encountering the trojan. Were you prompted to reinstall Windows from the beginning? It’s possible you have a remnants folder containing earlier setup files.
The best approach is to begin anew and reinstall Windows from the ground up. If you're especially cautious, before installing, use the command prompt in the Windows PE installer to access the disk partition and execute a `clean all` command on the target drive to completely erase it. This will delete any existing files and securely remove infected content. When the installer launches, press `Shift + F10` to open the Command Prompt, type `diskpart`, press Enter, then type `list disk`, press Enter to confirm the boot drive number, select it with `select disk x`, type `clean all` and press Enter to erase the drive. This process may take several minutes based on drive size. Type `exit` and press Enter to close the window, then proceed with the reinstall.
