jukaraso.dll
 

Quando accendo il pc mi dice che non riesce a trovare questo file

ho letto in giro che potrebbe essere un virus ma non capisco il perchè allora lo cerchi come file di sistema... infatti come directory mi da la windows32 system..

qualcuno ne sà qualcosa?

ho fatto già diverse scansioni.... sono sotto attacco massicio di trojan da un pò di giorni.... ah sono ben accetti anche buoni software...


grazie

jukaraso è un trojan. Il sistema lo cerca perchè evidentemente ha fatto bene il suo lavoro, sostituendo qualche file di avvio.
Scarica hijackthis, fai una scansione e posta il log.
Nessun antivirus o spyware detector ha la minima efficacia.

????

sempre con hijackthis cancella la riga:

O4 - HKLM\..\Run: [nosuyeberi] Rundll32.exe "C:\WINDOWS\system32\jukaraso.dll",s

se non sbaglio c'e' un check-box che puoi selezionare e poi un pulsante per "pulire"...

O20 - AppInit_DLLs: C:\WINDOWS\system32\sozewema.dll

dll dubbia....sicuramente e' un virus, togli pure quella.

vi ringrazio moltissimo!

non mi da più l'avviso all'accensione ;-)

Ogni virus crea una propria chiave di registro, così da poter essere caricato ad ogni avvio del sistema. Hijackthis ti permette di rimuoverla così da rendere il virus inattivo.
Occhio però a far visionare sempre il log, in caso, da qualcuno competente, perchè se si cancella la chiave sbagliata sono c...ehm, dolori! :);)
