AVG e Windows Defender inattivi dopo esecuzione file infetto [era:Qualcuno mi aiuti]

[magisox]

Da qualche giorno dopo aver scaricato un file da emule mi è scomparso l'antivirus avast, o meglio è presente l'icona ma non parte (viene fuori la finestra con la torcia e viene scritto che non è stato trovato nella sua directory). Ho provato a scaricare AVG e ad installarlo ma dopo averlo installato non ho trovato il programma sulla barra dei programmi. Windows defender non va più, mi dice "impossibile inizializzare l'applicazione.....". In più il computer non va più in modalità provvisoria. Come posso tentare di risolvere il problema? Grazie

[tecnico24]

scaricati hijackthis da qui---> http://www.angololibero.it/software/...ijackthis.html
avvialo,clicca su do a system scan and save logfile,fara una piccola scansione,uscira' un logfile con delle scritte,riporta tutto qui con un copia|incolla.

si trattera' del worm bagle che disattiva antivirus/firewall e modalita provvisoria.

ciao magisox,nel log non vedo la presenza di bagle,ma c'e qualche schifezza.
procedi cosi:

avvia hijackthis,spunta a sinistra su queste voci:


O4 - HKLM\..\RunOnce: [avp6_post_install] msiexec.exe /i"C:\DOCUME~1\Matteo\IMPOST~1\Temp\Rar$DI00.140\av s10.msi"
O2 - BHO: (no name) - {7E853D72-626A-48EC-A868-BA8D5E23E045} - (no file)


poi clicca sotto su FIX CHECKED.

poi
Scarica The Avenger
http://swandog46.geekstogo.com/avenger.zip

Poi avvia il file Avenger.exe.
Seleziona l'opzione Input Script Manually, clicca sulla lente di ingrandimento e all'interno dello spazio bianco copia ed incolla queste scritte:


files to delete:
C:\WINDOWS\system32\BtUsrBdg.exe


dopodiche clicca su done,poi sul semaforo,due volte si,riavvia il pc,e rispondendo al forum posta il logfile di avenger che lo trovi in c:/avenger.txt
la situazione migliorera'....

Ok, devo fare qualche altro passo?Antivirus e windows defender sono ancora bloccati..

Grazie mille dell'aiuto che mi stai dando...

[tecnico24]

hai fixato le voci che ti ho detto sopra?

[ste_95]

ho due domande..

la prima: hai tralasciato due righe di inizio dello scan...

la seconda è quale versione di hijackthis hai usato per lo scan? se la 1.99 usa la 2.0.2 per farne un'altro, vengono evidenziate molte più cose...

Si ho fixato le righe che mi hai detto...La versione è la 2.0.2.

[ste_95]
