After I installed the Avira, I also installed Adobe Flash Play (or
whatever it's called) and also Adobe Reader 9.2. After the updated
Reader installed, I got a message I have never gotten before,
something to the effect that the computer needed to be defragged for
the program to run correctly. I had just defragged it last week but
defragged it again.

At the end of the defragging, I got a report that said some files
couldn't be defragged. This, also, is something new to me. I have the
report (below), but it contains nothing useful (?). Would the former
anti-virus program, AVG, have filled the computer with "un-
defraggable" files? It's the only program I added to this very small
hard drive (10 GB on one partition, 10 on another).

Thank you.
