Nobody can comment, I'm afraid, on something that's unknown. And if you don't tell the details of that NX.exe (folder, details in properties and if it is related tot the recovery you run) nobody can comment on that either.
I was browsing through Task Manager and I saw 2 unknown.exe processes and a NX.exe while I was running recover my files to try to recover my data from portable hard drive.
they were using 40% of my processor and my cursor was also scrambled.
