aiuto per eliminare virus

[back in black]

ciao a tutti

ho bisogno di aiuto per ripulire il pc di mio fratello che ultimamente ha continui rallentamenti e pop-up in continuazione durante la navigazione, premetto che in materia sono totalmente ignorante, ho fatto una scansione con ad-aware e con avg antispyware (versino free) e ho eliminato un po' di spazzatura poi una scansione con l'antivirus avf free edition e ha trovato 64 file, la maggior parte dei quali si chiamaswizzor e me li ha messi in virus valut, ora come faccio a eliminarli?
mi convine usare qualche altro programma per fare pulizia?

Questo programma in versione freeware
http://www.superantispyware.com/
Installi, aggiorni e poi fai un controllo di tutto il disco.

grazie, adesso lo provo subito

però come faccio a eliminare i file trovati dall'antivirus?

[crazy.cat]

ci dovrebbe essere una funzione per svuotare il cestino, o la quarantena, non uso avg e a memoria non ricordo.
In quella zona sono stati resi innocui per il momento.

sembrerebbe tutto a posto...ho visto che molti fanno la scansione con hijack this dici che è il caso la faccia anch'io?

[ste_95]

Postalo pure:

Scarica HijackThis
Salvalo in una cartella (non aprirlo direttamente, sennò non farà i backup!)
Apri l'eseguibile
Clicca quindi su "Do a System Scan and Save a Logfile"
Attendi che finisca la scansione
Quindi copia il contenuto del blocco note qui sul forum.

Ecco il log

Questa mi insospettisce:

O4 - HKCU\..\Run: [List Ref] C:\DOCUME~1\Federico\DATIAP~1\BAITON~1\EncPlay.exe

Cerca il file e scansionalo su www.virustotal.com e riportane i risultati.

[back in black]

lo stavo uplodando su virustotal quando antivir(cho ho appena installato) mi ha trovato un virus, l'ho eliminato e il file da analizare è sparito dalla cartella
anche avg me lo ha trovato un po' di volte ieri ma continua a tornare adesso se torna non lo elimino e lo analizzo con virustotal

[back in black]

caricato su virus total ma ci vorranno dai 200 ai 290 min

p.s. leggavo su altri siti cercando info sul virus che prima di usare hijackthis dovevo eliminare i punti di ripristino o qualcsa del genere...io non l'ho fatto...potrebbe aver compromesso i risultati della scansione?

[ste_95]

No, non ha compromesso nulla, disattivalo ora.

Verifica se all'interno della cartella Dati Applicazioni è presente anche un'altra cartella con un nome strano.
