Ho liberato il pc di un amico da una serie di spyware, virus e dialer, ma nonostante abbia fatto una pulizia accurata con avast,spybot,noadware e spysweeper, continua a rimanere un problema sul desktop :
in pratica non carica piu lo sfondo e di conseguenza anche il menu "proprietà", bensi rimane una pagina nera con scritto : "warning!you're in danger!", e clicckandoci sopra riporta ad un sito web molto "losco" che promette di eliminare le spyware. il sito a cui rimanda e' www.topantispyware.com
Vi posto il log di hjackthis :
