Trojan Win32:Small-BWI(Trj)


(Asz) #1

Cześć.

Niestety złapałam jakieś paskudztwo. Przy prawie każdym uruchomieniu komputera lub przelogowaniu na innego użytkownika avast krzyczy, że znalazł Win32:Small-BWI(Trj) (c:\windows\system32\winhst32.exe). Usuwam go, ale chyba tylko pozornie.

Poza tym od czasu do czasu pojawia się komunikat:

Krytyczna luka w oprogramowaniu Microsoft Q77434, Q77435.

Komunikat zaczął pojawiać się w tym samym czasie co wirus. Wszystkie aktualizacje do XP mam zainstalowane.

Zgodnie z zaleceniami wklejam loga z hijack-a i proszę o sprawdzenie.

Mam jeszcze pytanie: czy muszę uruchamiać hijack-a dla każdego użytkownika? Widzę, że się trochę różnią.

Na razie wklejam jednego:

W trybie awaryjnym z wyłączonym przywracaniem systemu usuwasz (wpisy Hijackiem, pliki/foldery na czerwono ręcznie z dysku):

Po zabiegach nowy log z Hijacka + log z Silent Runners


(Asz) #3

Dzięki, zaraz tak zrobię.

Tylko mam problem z Silent Runners. Ściągnęłam plik “Silent Runners.vbs”, niestety podwójne kliknięcie nie uruchamia programu, tylko otwiera okno z pytaniem czym ma go otworzyć. No i z czym?

O błędach Silenta poczytaj tutaj -> http://www.searchengines.pl/phpbb203/in … opic=15989


(Asz) #5

Dzięki, zaraz poczytam.

Usunęłam wpisy i pliki (mam nadzieję, że dobrze).

Teraz wklejam nowego loga.
