Virus autorun.inf recycle
To check if the virus is in your computer:
1. Go to command prompt.
2. Type CD\ in drive C to go the root directory
3. Type DIR /AH and press ENTER key. This will display all hidden files in your drive C
4. If you see a file AUTORUN.INF and a folder Recycled, then your system is infected.
5. Try doing this to your USB drive and check if your USB stick contains the same folder and AUTORUN.INF, if it does then your system is really infected.
To remove the virus:
1. Boot your system in Safemode
2. Go to command prompt, in Drive C do the following commands.
3. Type -> ATTRIB -H -R -S AUTORUN.INF then press enter
4. Type -> DEL AUTORUN.INF then press enter

6. In Windows Explorer in Safemode, remove the folder Recycled in drive C use Shift-Delete to delete the folder.
7. Repeat Step 3 to 6 for all drives of your system including the USB drive.
8. Search for CTFMON.exe in your system using the Search of Windows found in Start Menu. If you find a file that is not located in C:\WINDOWS\SYSTEM32, delete it immediately. Dont forget to empty the recycle bin afterwards (Usually the virus will copy itself in the Startup folder of the Startmenu. Check if the file is present there and delete it then.)
To disable autorun of drives (i.e. everytime you double-click a drive or cd or usb, it is auto open) follow the following step:
1. Click Start->Run->type REGEDIT.exe
2. Go to this key from the register HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer

Algumas músicas do iTunes deixaram de funcionar depois de instalar o iTunes8
Durante a modificação das tags das músicas (nome, intérprete, capas, etc.), o iTunes alterou a tag do ficheiro de maneira que depois nem ele consegue ler o ficheiro.
Fazer o download de www.mp3tag.de, seleccionar a música e no menu: Ficheiro > Remover tag
Fazer o download de www.mp3tag.de, seleccionar a música e no menu: Ficheiro > Remover tag
Porque não consigo ouvir as músicas da minha biblioteca iTunes noutro leitor MP3?
As músicas podem ter sido importadas para o iTunes com um codificador diferente do MP3.
Para de futuro poder partilhar as músicas importadas para o iTunes com outros leitores MP3: menu iTunes: Editar > Preferências... > Geral > Definições de importação... > Importar usando: > Codificador MP3
Para converter para MP3 músicas já no iTunes: seleccionar a música, menu iTunes: Avançadas > Criar versão MP3
