Everyone has it...we all need it....but........I don`t recommend using version 10. Some people have mentioned problems with chat sites and various other sites after installing the version 10.
The music player in my pages is reliant on Flash but I have noticed a few glitches when I have version 10 on my system (songs playing back garbled etc) so if you notice this problem try reverting to version 9 of Flash-it worked for me.
Here is a link for an uninstaller:

Here is a link for version 9-or find another source of downloading it.
