Un Trojan che si riforma da solo

[ikaris]

Ho VISTA PREMIUM e AVAST come antivirus.

Sono 3 giorni che avasto mi trova, ogni 2-3 ore, un trojan. Senza che io stia scaricando niente!!!

Attualmente mi ha trovato questo: 74exhdda.exe
sempre su C:\users\roberto\appdata\local\temp

mi si formano in continuazione e li metto nel cestino di AVAST per poi eliminiarli ma poi ritornano. Ho anche svuotato tutta quella Cartella TEMP ma non ho ottenuto nulla.

Cosa posso fare?

GRAZIE

Basta lanciarlo e torna tutto a posto?

Scusa ma non sono esperto, non capisco come usarlo

Un'altra domanda: Cosa posso usare per prevenire questi problemi avendo VISTA PREMIUM

Io ho AVASTA e il Firewall di VISTA ma deduco che non sono il massimo

Come faccio ad eliminarli?

una volta fatta la scansione con Hijackthis, li selezioni ( flagghi il quadratino alla sinistra dei file che ti ho detto) e poi clicchi il tasto " Fix checked".

Grazie ai vostri preziosi consigli ho risolto il mio problema.

Ancora molte grazie per la vostra disponibilità

Ora mi chiedo in ultima analisi:
poichè "prevenire è meglio che curare", cosa mi consigliate di montare su VISTA PREMIUM per avere una adeguata protezione?

Attualmente ho AVAST + WINDOWS DEFENDERS costantemente aggiornati

Rileggendo mi sono accorto di avere tolto C:\Users\Roberto\AppData\Roaming\smss.exe
