I downloaded a program and found out that I cannot delete it. Every time I turn on my pc It comes out and every time I log out, it stay on on my pc. So, I deleted it and then I discovered that all my programs became a executable link.
restart your pc and while it is restarting click F8 until it goes to safe mode. Select a date before and click and it will start restoring from the date you selected and follow what ever it tells you to do
