Olá -Samanta-,
O logfile está limpo, o problema persiste?
Abraços.

Olá . Não , a pasta já ñ aparece .
Muito obrigada .

Tenho apenas mais uma dúvida . Na barra inferior (julgo que se chama barra de tarefas ?) aparece um género de interferências como se a barra fosse desaparecer . Ontem , quando utilizei o programa anti-malware , a barra quase que não aparecia , mas voltou a aparecer . Sabe o que posso fazer acerca disso ? Ou se tem algo a ver com os malwares ?
Espero ter conseguido explicar direito .

Obrigada .

Olá -Samanta-,
