No mention of computer model and make, nor size of the two hard disks or any other details.
What does "Computer" show when you open it?
What was this 60GB you deleted and how did you delete it? Is all that data still in the Recycle Bin? if so, delete it from there as well. That is like emptying the Trash out of your household trash bin. Until you empty it, it is still in your possession.
I don't put anything on d drive and I deleted 60 gb on c drive but still shows less than 200 mb left ran every virus program I can think of still nothing, System restore is turned off, not sharing anything, I rolled the pc back to start of month and everything was good then 2 days later I'm getting the warning pop ups again. Any idea what could be the problem
