Program to erase (permanently) empty hard-drive space using multiple random rewrites
This is part of a file shredder utility.

Eraser is a secure data removal tool, which allows you to remove sensitive data from your hard drive by overwriting it with carefully selected patterns.

Great eraser program, use with caution, files once erase cannot be recovered.

Program which 'shreds' files you want to delete so no one can read them afterwards
  Darren   (further information)
It is a shredder program, it is freeware and not part of windows period. It was on a "Maximum PC" Magazine And probably available on the Net as well. You can disable the "eraser.exe -hide" command it puts in your config file and still use the program.
File "shredder" that removes files from your hard drive in a way that they can never be accessed again by any program.

Up to now this is the second (or third) time I have downloaded the program from a site where it was mentioned in a publicity banner as "clean your PC with Eraser.exe". Some years ago I installed this program on my PC and a few days ago on this laptop. If I recall well, a few years ago, this wasn't that hard to remove and wasn't classified as malware (note : I could be wrong). I found it on a dvd with trusted freeware software (like AVG, Works, etc.) Only today I noticed it is most probably cause to slow down my system. The reason could be that, since I've downloaded it a few days ago, this program is launched from start-up. In the Task Manager I found it in the Start-Up programs, along with my anti-virus program. Therefore, I suppose there might be a conflict with my antivirus program (BullGuard). What is remarkable is up to now, it hasn't been found by BullGuard as threat - I wonder what other Anti-virus programs are mentioning (some info please). I will try removing it from my laptop with your program, with BullGuard, manually or with another program.

Best practices for resolving Eraser issues

A clean and tidy computer is the key requirement for avoiding problems with Eraser. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
