I have an HP Pavilion 590-p0044 Desktop PC running Windows 10 Home 64-bit. I have the My Book 1230 4 TB USB drive that I use for backing up my system with Easus ToDo Backup Free. On 09/04/2019, I had downloaded the ZIP file for the portable application “Windows Repair Toolbox” and saved it to my USB drive. This past Monday, 10/14/2019, I ran the executable file from my USB drive, and numerous files were downloaded to that drive for use with the toolbox. About 5 hours following this, I received many pop-ups from Windows Defender (my only security program) indicating that Windows was now infected with about 10 instances of HackTools and 2 of Trojan:Win32/Nedsym. Defender linked me to Windows’ website for instructions on removing each. I followed the instructions explicitly, and according to Windows Defender and Microsoft Safety Scanner, all infections have been removed completely. I am here because I would like to recover Windows using an image I had created wtih Easus and stored on my USB drive in 08/2019, and would like to find out if that is even possible with these infections.
