Ciao a tutti!

Devo sistemare un pc; sapete per caso se il file mun.exe sia legittimo? Non so se rimuovere le relative voci da questo log di hijackthis:

Le voci in particolare sono queste:

C:\ProgramData\Microsoft\Windows\Start Menu\Programs\StartUp\mun.exe
O4 - Global Startup: mun.exe

Il problema del PC è, essenzialmente, che navigando con Google Chrome si aprono pagine pubblicitarie su Internet Explorer, e ogni tanto si apre un avviso su un qualche script che mi chiede se eseguire . Ho fatto svariate scansioni (malwarebytes, kaspersky virus removal tool, tdsskiller, bitdefender free, adwcleaner); l'ultima con Junkware removal tool l'ho fatta poco fa, ho riavviato il pc, e per ora sembra che non si aprino pagine pubblicitarie, però si è aperta quella richiesta di eseguire lo script.

Che dite, le rimuovo quelle voci relative a mun.exe? Ho provato a cercare sto benedetto file mun.exe per provare a caricarlo su virustotal, visualizzando anche file nascosti e file di sistema, ma non riesco a trovarlo nel relativo percorso

[crazy.cat]

direi niente di buone ne di utile
http://www.threatexpert.com/files/mun.exe.html
cancella pure.
Puoi far vedere la fato di questa richiesta di script?

[Pct]

Grazie per la risposta Crazy! Allora elimino quelle voci; quanto alla foto della richiesta script, purtroppo prima non l'ho fatta; se succede di nuovo la faccio! Ho provato a riavviare il pc e ad aprire chrome per vedere se succedeva di nuovo, ma per ora non è successo

[Pct]

E' successo adesso, ecco qua l'immagine:

Sembra un sito pubblicitario, un motore di ricerca fasullo.
Site Title: 7Bow - Rede de Publicidade Online
Controlla i motori di ricerca presenti, le estensioni di chrome e vedi se trovi qualcosa.

[Pct]

Si, avevo già "resettato" tutte le impostazioni di chrome ed IE, e controllato estensioni e motori di ricerca, e non c'era nulla di strano (probabilmente per via del reset); da quando ho tolto quella voce di mun.exe non si apre più nessuna pagine pubblicitaria né quella richiesta di script! Sembra tutto risolto, grazie mille dell'aiuto Crazy!
