Winlogon.exe - atak na Firefox (lub IExplore)


(Jacek25jw) #1

Mam zainstalowaną zapore Kerio Firewall i mniej wiecej co 2 godziny pokazuje mi, ze proba ataku "winlogon.exe" na "firefox.exe" (lub iexplorer - w zaleznosci co jest uruchomione) została zablokowana.

Log z programu:

"Process\??\C:\WINDOWS\system32\winlogon.exe incjected dangerous code into C:\Program Files\Mozilla Firefox\firefox.exe (code address: 0x7FFA0065)"

O co tu chodzi? winlogon.exe atakuje przeglądarki?

Przy probie zakończenia procesu winlogon.exe wyskakuje, ze jest to "krytyczny proces systemu". Co z tym zrobic? Czy to jest grozne?

Zastanawia mnie jeszcze co oznaczaja te znaki zapytania w sciezce po "Process\??\"?

Przeskanowalem antywirusami (zwykłym i on-line) i żaden nic nie wykrył. Logi z HijackThis też nic nie pokazały.

Jak ktos mi moze pomoc i wyjasnic dlaczego tak sie dzieje to z gory dzieki

To znaczy,że masz syfa a winlogon.exe został zainfekowany. Jesli nie bedzie ich widać to prawdopodobnie to rootkit

Aby sprawdzić koniecznie daj loga z Hijacka i SilentRunners.

Dzieki, ale Twoja wypowiedz niewiele mi pomogla :frowning:

Po zrobieniu powyższych wskazówek jeszcze zrób to:

Wklej to do Notatnika:

Plik => Zapisz jako => Ustaw roszerzenie na Wszystkie pliki => Zapisz jako FIX.REG

W trybie awaryjnym uruchom FIX.REG i restart komputera

Pózniej Gmer tak jak InfityToja napisał.

Juz wiem gdzie był problem. "InfinityToJa" nakierował mnie i usunałem brzydki plik "wineak32.dll". Poza tym "ewido anti-malware" wykrył duzo smieci w katalogu przeglądarki. Jeszcze tylko nie wiem gdzie to złapałem.

Dzięki wszystkim za pomoc :slight_smile:
