How to restore "MS Excel" to the default settings

Sometimes happens that for some reason Excel starts functioning as he wants, you can reinstall, repair, and nothing, the follies of excel do not cease to happen.
That is because although you reinstall or repair the excel this always keeps the configuration it had at the time of malfunction.
For that we need to delete the faulty settings and then once deleted the configuration excel will start again with the default configuration that comes when you install it for first time.
To delete the configuration of EXCEL completely you have to close it first, now just have to delete the following registry path windows.
[HKEY_USERS\\S-1-5-21-THISCANCHANGE-1003\\Software\\Microsoft\\Office\\12.0\\Excel\\Options]
Ahi borramos el directorio "Options"
When Excel is open again will restore all settings to factory default it brings

For those who wonder how to enter the Windows registry, this is done by going to "Start Menu>> Run" and type "REGEDIT", when run will open the "Registry Editor".

How to restart Gnome without rebooting the entire PC

One of the bigs problems in linux is the graphic interface, those who use Linux and never hang Gnome is because is doing something wrong. Here, I explain two ways to restart GNOME without rebooting the entire PC.

Mode 1: Open a console with "Ctrl + Alt + F2" (I use F2 but you can use another F). In the console type:
sudo /etc/init.d/gdm restart
the GUI would have to reboot and reload.

Mode 2: Kill violently Gnome panel. In a console type:
killall gnome-panel
After this we return to the interface by pressing "Alt + F7"

SOLUTION: KlamAV error "the database directory must be writable for UID 1000 or GID 1000"

In a great moment of Lucid I thought my ubuntu install an antivirus, I tried AVG (never installed it), then go for AVAST (it works though its interface lacks mature a lot) and finally install KlamAV which is perfect but when updating the virus database gave the error "the database directory must be writable for UID 1000 or GID 1000".
After much searching on google I found the solution, and rename the directory where you saved by default updates the database and after that the program will propose a new directory where you save and update without problems.

SOLUTION:

1) Close KlamAV
2) Open a terminal and type the command: sudo mv /var/lib/clamav /var/lib/2clamav
3) Open KlamAV. when it intends to use the "/home/username/.klamav/database" indicate "YES"

With this the KlamAV would have to update the database without problems

SOLUCION: KlamAV error "the database directory must be writable for UID 1000 or GID 1000"

En un gran momento de lucides se me ocurrió instalar el mi ubuntu un antivirus, probé AVG (Nunca se instalo bien), luego pase por AVAST (funciona aunque a su interfaz le falta madurar mucho) y por ultimo KlamAV el cual se instalo perfecto pero al momento de actualizar la base de datos de virus daba el error "the database directory must be writable for UID 1000 or GID 1000".
Después de mucho buscar en google encontré la solución, y es renombrar el directorio donde se guardan por defecto las actualizaciones de la base de datos y luego de esto el programa propondrá un nuevo directorio donde guardarlas y se actualizara sin problemas.

SOLUCIÓN:

1) Cerrar el KlamAV
2) Abrir una terminal y escribir el comando: sudo mv /var/lib/clamav /var/lib/2clamav
3) Abrir KlamAV. cuando proponga utilizar el directorio "/home/nombredeusuario/.klamav/database" indicarle que "SI"

Con esto el KlamAV tendría que poder actualizar la base de datos sin problemas
