Did you install suspicious programs from unknown websites or open an unknown attachment file in an email in recent days? If yes, be alert. It's pretty sure that it's the virus that eats up your hard drive space!
Step 1. You can run the anti-virus software on your computer to scan and remove the virus for the first attempt.
Step 2. If virus removal software doesn't work, try to use cmd to remove the virus from the hard drive.
Step 3. What's the last yet the most powerful way to remove a virus? Fully format the hard drive or do a system restore.
- Hard drive formatting and system restore can somehow kill the stubborn virus, but at the same time, erase your important data. Consider backing up the data before you take the last chance to stop the hard drive from losing the free space very fast.
Let's check if the System Restore is turned on, for example, in Windows 10. Go to "Control Panel" -> "System and Security" -> "System" -> "System protection". Click the System protection to open "System Properties", where you could see the "Protection Settings".
Usually, the Protection is set to 'On' for the System drive. And that's how your hard drive lost free space more and more rapidly. This feature is creating and storing your computer system files and settings on a regular basis and kept in restore points, which are large files.
If this is the problem you care about, you can either choose to directly disable the System protection feature by setting the Protection to 'No', or take the other two steps.
Download EaseUS CleanGenius on your computer. It's also widely used as a disk cleanup utility. You can use it to clean up system junk files, clean large files, and optimize a disk, all of the three options are meant to fix the 'hard drive losing space' issue efficiently.

Step 4. When the scan is complete, click "Done" to finish cleaning system junk files.
Step 2. After freeing up the disk space, you may still wish to enable this system protection feature because it plays a vital role in future system restore and repair. On the regard, it's a good idea to reduce its disk space usage in this way.
- Open System Protection tab and select Local Disk C: (System) under the Protection Settings tab in the same way. Click "Configure".
- Turn on system protection there and under the Disk Space Usage section, move the slider to reduce the amount of disk space System Protection can use. As space fills up, older restore points will be deleted to make room for new ones.
- Click the "Apply" button.
This is where you can also delete all restore points for this drive. It's estimated that this method will help save at least 10 GB disk space on the target drive. Don't hesitate to have a try.
