I clicked the link it gave me in the message and installed it.

Then I had to go to "devices" within my OS in the virtual box and update guest editions

voila ... done

There is usually no need to do any defrag or disk clean up, unless you are in dire need of extra harddisk space. You can run:

Code:

sudo apt-get autoclean

to clean out old packages.

There is no need to defrag unless you have a fat32 partition lying around. There is no need to check for virus.

You can clean out your browser's cookies and cache.
