I have an Acer netbook and this is a photo of a folder open on the screen.
Down in the bottom right hand corner of the folder is a square with a circle in side it. It first appeared a few days ago and I have no idea what it is or where it has come from. It doesn't seem to do anything. I ran a scan just to be on the safe side but that showed nothing untoward was trying to wreck my computer. Also, each time I start the netbook a notepad page appears on the desktop titled "Debug." When I open it it is empty.
It is running on Windows XP as is my main computer which has nothing like it on any of it's folders.
If there is anyone out there who knows what these are could you please enlighten me.
