Ok

i have a
:Toshiba Satellite P300

And when i am working on anything sometimes i see this dialog box flash in the bottom right corner. and it flashes so fast i cant read the text or see what it was about

i don't think this is a virus i have done full scans
With:
Avira
Malewarbytes
Microsoft Support Emergency Response Tool
Microsoft Windows Malicious Software Removal Tool

And nothing has come up
so some suggestions as to what this may be would be greatly appreciated

One of your programs has been set to display a dialog box when it has done something, for example , i have my Yahoo IM set to show me a pop up box when someone IM 's me.
You probably just forgot which one it is, and it probably is no big deal, as you have performed scans and ruled out malware.
