[Win7x64] Virus che non fa andare su internet e blocca mod. provv.

[tarty88]

Ciao a tutti,

Antivirus: Avast free + Malwarebyte's PRO

Questa mattina navigando su internet ho preso, senza alcun preavviso, questo virus. Non è stato rilevato dagli antivirus e non riuscivo + a navigare in internet, sempre errore di connessione, sia su firefox che su IE. Mi sono poi accorto che anche skype e i giochi online non trovavano la connessione internet. il pc era tuttavia connesso. Accendo l'altro pc e internet va e lo smartphone naviga. Deduco che è un virus. faccio partire Malwarebyte's e avast e non trovano nulla. Provo ad entrare in modalità provvisoria e non mi fa entrare, si blocca (tutt'ora) a CLASS.qualcosa nel caricamento dei files di windows.
Provo quindi a fare un ripristino della config di sistema e risolvo il problema, torno a navigare.

Poi ho scaricato spybot, prevx, hitkackfree, ho scansionato con tutti almeno 2 volte (compresi avast e MBAM) e non trova nulla...

Tuttavia il pc non va proprio forte come prima, soprattutto nel caricamento delle cose (outlook, giochi, windows stesso). e' colpa del ripristino o può essere che sono ancora infetto?
Mi conviene formattare?

Vi ringrazio

Aggiornamento: dopo aver usato il pomeriggio, l'ho spento. Ora lo riaccendo e mi trovo spybot corrotto, non ci sono più i files eseguibili e ho dovuto reinstallarlo... brutto segno?

Ho scansionato con Dr.Web e ha trovato e neutralizzato questo:

C:\Windows\System32\drivers\etc\hosts possibile DFH.HOSTS corrupted

Come posso capire se sono effettivamente libero dal virus?

Aggiornamento: Ora riesco anche ad entrare in modalità provvisoria, non si blocca più

potresti fare un analisi con hjackthis
http://www.filehippo.com/it/download_hijackthis/

per verificare se sei realmente pulito...

in più farei una scansione con un rescue disk,ad esempio kaspersky


http://rescuedisk.kaspersky-labs.com..._rescue_10.iso
,avviare il pc da cd,e fare una scansione da cd live.

ho fatto una scansione bloccando gli altri antivirus ma sinceramente non capisco che benefici abbia portato... Cosa fa?

Cancella i virus che gli antivirus normali non trovano...mi ha salvato il PC in diverse occasioni
