Hi,

I have just noticed that my C drive is getting full, whereas it still had 30 GB free space 3 days ago.
Given last days activity I can't find any reason for this.
Now I realize that my C free space is getting lower and lower whereas there's no current activity on my PC (except that it's turned on).
Every 2 minutes, I lose approximately 100 MB of free space, whereas I don't download anything.

Could it be windows update? How can i check this?
Could it be a virus or something bad?

Please, answer quickly, i only have 17GB left :-(

Thanks

I launched my antivirus and I have closed my internet connection in order to see if the free space would stop decreasing, but it continued decreasing at the same pace.

I checked the task manager and notice there was a software running which I think was named "One Drive setup.exe" (during the past weeks, I had many pop up windows saying I had to update onedrive, but there was a problem with the auto update etc... but I didn't car because I don't even know what OneDrive is and I don't think I use it). So I killed this running task.

I thought it had stopped the loss of free space (I even gained 100 MB), but the decrease started again.

Now I connected to Internet again.

I got 300 MB free space back and now it seems constant since 4 minutes. Maybe these little ups and downs can be due to the current antivirus scanning.

But what can explain the loss of 30 GB during the past 2 or 3 days?
