Innanzitutto grazie per l'aiuto

Comunque anch'io ho provato a fare la scansione con avira in modalità provvisoria e non ha trovato niente.

Vedo che non sono l'unico ad avere questo problema, quindi volevo chiedervi se anche voi avete il sospetto di averlo preso su facebook.. ??

Ciao, navigando mi è comparsa un' icona nella barra delle applicazioni con un punto esclamativo rosso su sfondo blu e di seguito scritto "copia in corso.."

Non si può chiudere, anche perchè cliccandoci sopra non succede nulla.

Non si può spegnere il computer e se lo si fa brutalmente al riavvio riappare.

L'ho scansionato con HijackThis, riporto di seguito il log

Grazie a tutti in anticipo
