[virus?] parole strane sul browser

[Greylines]

Salve a tutti, sono un nuovo arrivato sul forum e ho un problema da porvi: sul portatile di mio padre capita ogni tanto che in certe frasi le parole vengano stravolte. In particolare certe parole vengono scritte in maiuscolo, viene aggiunta una maiuscola all'inizio e di tanto in tanto compare, sempre in maiuscolo, la scritta "NAZIONI UNITE". Succede solo sul browser (Mozilla o IE) e non sempre; io sono riuscito a vederlo una volta sola e ad essere modificate erano le mail su Virgilio ma lui mi ha detto che a volte capita anche col testo di altri siti (La Repubblica, per esempio). Ho subito pensato a un virus ma Avira aggiornato non ha trovato nulla.
Qualche idea?
Grazie.

Seleziona e fissa questa voce...l'unica sospetta...

F2 - REG:system.ini: UserInit=C:\Windows\system32\ezShellStart.exe

Hai scansionato con Spybot?

[Greylines]

Non ancora, non ho più avuto modo di mettere le mani su quel PC. Appena riuscirò posterò anche quei risultati e nel frattempo fisso la voce che mi hai segnalato.
Grazie fin da ora.

Greylines

[Skass89]

ok...aspettiamo tue notizie

[Greylines]

Ho fissato la voce mentre la scansione con Spyboot ha trovato 6 cookie (traccianti e un dialer). Per ora sembrerebbe tutto a posto quindi grazie ancora.

Greylines

[Skass89]

di niente!
