Mi son beccato un virus-mirc

[Vash_85]

Salve a tutti ieri sera mentre cercavo della roba sulla rete per sbaglio ho aperto un exe sconosciuto che c'era in un archivio (mai successo che facessi una cavolata del genere) ed è subito partita l'installazione di una specie di mirc che si è installato in c:\windows... e subito mi è partito il mirc moddato... ho fatto una scansiona con avira 8 ma nulla... allora ho disabilitato il ripristino di sistema, cancellato tutta la cartella ed eliminato il programma dall'avvio automatico nel reg di sistema... sicuramente ci sarà qualche traccia di quella schifezza da qualche parte... il pc apparentemente non da più segni di essere infetto ma non i sa mai... inoltre mi stupisco che avira non abbia trovato nulla....anche lo scan di hijackthis è pulito.. suggerimenti per dare una bella pulita di sicurezza?

dal log, come hai già visto tu, non si vede nulla...
Per fare un controllo leggi le regole di sezione (http://www.hwupgrade.it/forum/showthread.php?t=1751598) e poi segui la guida alla disinfezione per infetti (http://www.hwupgrade.it/forum/showthread.php?t=1599737) ed esegui tutte le scansioni ed il caricamento dei relativi log nelle modalità e nell'ordine indicato.

Recuperato il file di setup originale e mandato a scansionare questi sono i risultati

Che ne dici?

[wjmat]

potrebbero essere i classici farli positivi come quelli di mirc....
potresti far controllare, per paragonarlo, l'eseguibile originale di mirc ;)

[Vash_85]

Fatto... è proprio uno pseudo virus...adesso l'ho spedito ad avira per vedere loro che dicono....aspettiamo
