For a while now soon about 45 mins after I start up my computer a window appears towards the top left of the screen which is very small. So small that the minimise and maximise icons are very near the left hand corner of window; I cannot see the content of the window itself. The icon in the top left hand corner is the icon related to the application I was last using.
The computer then becomes unresponsive; then the screen goes blank. After a second or two the screen is restored except thatn in the bottom right there is a large black box. To get rid of this black box I press ctrl-alt-delete and then hit the cancel button; the screen is then restored.
I was using the procmon.exe to track what was happening on the system but this crashed just at the moment I needed it.
What tool can I use to record audit of applications starting and stopping on the laptop so that I can figure out whether I have a virus or not?
