I don't what I did but every program that ends with .exe runs with my Adobe Acrobat. For example, when I try to open up Windows Media Player, Acrobat opens up with this message:
"Acrobat could not open 'wmplayer.exe' because it is either not a supported file type or because the file has been damaged (for example, it was sent as an email attachment and wasn't completely decoded).
To create an Adobe PDF document, go to the source application. Then print the document to Adobe PDF."
Why in the world does my computer do this? I was trying to find a solution and discovered that this would help open an application: right-click application > "Run As..." > select the "Current user" option (with the bottom option about protection from unauthorized program activity unchecked; checking it restricts certain features of the Internet). By the way, I only have one account on this.
No program works automatically. Was this some thing I accidently did or the work of a virus? (Because I have no virus protection.) How do I change my computer back to its normal state?
