Su consiglio di Wolfstein metto il mio messaggio qui.

Dopo tutto l'Ambaradam l'intruso è scomparso all'80% ma non è debellato, ogni tanto riappare.

Ecco qui il mattone:

Salve, nel mio pc è apparso improvvisamente "Captchatest.top", che mi segnala con insistenza che nel mio pc è entrato un virus, l'antivirus è disattivato, il sistema è danneggiato, scansiona, elimina virus, installa tizio caio e sempronio, clicca qui e là e altre menate del genere, ovviamente non ho cliccato su nulla, probabilmente si tratta di un adware.

In rete ho trovato un mare di cose su "Captchaqualcosa", ma nulla su "Captchatest.top".

Sono ricorso alla guida di Giza e ho usato Malwarebytes, lancio la scansione e MB trova C:\Programfiles(x86)\Windows live\Photogallery\Winmoviemaker.exe classificato come "Generic malware suspicious", solo questo, forse è un falso positivo ma lo metto in quarantena.

Parto con AdwCleaner

Segui quanto suggerito da wolfe, se
Spy Hunter ti fa fare la rimozione gratuita di quello che trova, Provalo.
Riattiva Defender e fai una scansione completa, vedi ciò che trova.
Fai questa pulizia del Registro:
Per una pulizia profonda del registro, usa Eusing Free Registry Cleaner sw da usare saltuariamente, lo scarichi da qui: http://www.eusing.com/free_registry_cleaner/registry_cleaner.htm
clic su Download Site1, una volta lanciato appare una finestra che chiede il codice, clic su ignora e procedi, poi in alto a sinistra clic su Analizza Registro, lascia fare fino alla fine non ti preoccupare se trova molte voci, poi clicca su Ripara Registro, il sw è sicuro comunque crea un punto di ripristino e fa anche il backup dei file eliminati infatti in alto sotto ripara registro si trova la voce Ripristina Registro.
Per fare questa pulizia meglio chiudere tutti i programmi e disconnesso.
Il programma è compatibile con tutti i S.O. windows compreso win 10.

Dal log non si vedono grosse anomalie, ci sarebbero dei file da eliminare, ma prima fai quanto sopra poi dopo fai una scansione di HJT e posta il nuovo log.

Eseguito Spy Hunter per 3 volte.

Non lo ho usato per cancellare i file incriminati perché non voglio iscrivermi e perché, a mio modestissimo parere, elenca parecchi falsi positivi.
Come ho detto precedentemente con il primo passaggio l'intruso è sparito all'80%, passo a quanto richiesto da Cbbusto, in questo breve tempo di uso non ci sono stati disturbi.

Cancellato i primo messaggio come chiesto da Giza.

Così va già meglio. Ora fixa ed elimina le seguenti righe:

R0 - HKLM\Software\Microsoft\Internet Explorer\Search,SearchAssistant =

O15 - ProtocolDefaults: '@ivt' protocol is in My Computer Zone, should be Intranet Zone.
Alla fine pulizia con ccleaner e sei a posto.

Non mi è chiaro, devo "riparare" (fix) o eliminare quelle righe?
Come si fa a ripararle?
E se sono da eliminare che le riparo a fare?

Tutti segnalano il proprio percorso, tranne O15, come lo trovo?


Spiegami meglio per piacere.
P.S. fino ad ora l'intruso non si è più visto.

Grazie.

Nel giro precedente mi ero limitato a esaminare il pc e a comunicare il resoconto del Log.
Ho rilanciato HijackThis, di cui nemmeno ricordo quando e nemmeno se lo ho usato, cercando le opzioni che offre.
Ho visto che c’era il tasto Fix e lo ho lanciato.
Delle righe segnalate da Cbbusto sono rimaste solo le seguenti:

R0 - HKLM\Software\Microsoft\Internet Explorer\Search,SearchAssistant =
R0 - HKLM\Software\Microsoft\Internet Explorer\Search,CustomizeSearch =
O15 - ProtocolDefaults: '@ivt' protocol is in My Computer Zone, should be Intranet Zone

È rimasto O15, per cui richiedo di nuovo dove si trova.

In Hijack dopo la riga 011.

Ho cercato i due R0 nel percorso: HKLM\Software\Microsoft\Internet Explorer\ e non le ho trovate, HJT avrà eliminato anche loro.

In O15 non è indicato il percorso, allora ho lanciato una ricerca nel registro di sistema, e ho trovato questo:

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\ProtocolDefaults

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\ProtocolDefaults

Computer\HKEY_USERS\.DEFAULT\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\ProtocolDefaults

Computer\HKEY_USERS\S-1-5-18\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\ProtocolDefaults

Li devo eliminare tutti?

Per completezza incollo il secondo Log di HJT.

Si, ma i percorsi O15 dove si trovano i quattro "@ivt" che faccio?

Sono pericolosi o no?
