View Full Version : [Win7x64] Virus che non fa andare su internet e blocca mod. provv.
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
nessuno che sa darmi qualche indicazione?

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?
