Boas!

Tenho um portatil HPdv2542 com o XP media center edition devidamente actualizado. O portatil traz o norton internet security mas como é muito pesado, já a algum tempo que o tenho desactivado no arranque (pelo msconfig) e uso uma firewall (ashampoo -> visto que as outras todas que tentei, sygate, comodo nao funcionam, embora faça allow ao firefox e IE eles nao acedem a net). tenho o spyware doctor onguard.

o que se passa é o seguinte, desde a dois dias que me aparece qd tento no explorer abrir pastas (pastas de ficheiros, meu computador, meus documentos, painel de controlo, etc) uma msg ke diz "System error! your system is infected with a dangerous virus! Note: strongly recommend to install antipsyware program to clean your system and avoid total crash of your computer. Click "ok" do download the antispyware. (Recommended) ok cancelar" numa janela do windows, nao de nenhum browser. Se correr o IE ainda é pior porque é a cada click ou load. Ja corri tudo o que é antispyware (spywaredoctor, superantispyware, spywareterminator, ad-aware) nas ultimas versoes actualizados. Ate ja reactivei o norton e corri o scan. Nenhum detecta nada. Nem em modo de segurança. Pesquisei pela net e falam dum IE AntiVirus 3.2 mas nao encontro os ficheiros que eles dizem. Arrisquei e cliquei ok pa ver ke programa era e faz download de um programa "iav.exe" (que nao fix download).


abaixo segue o log do hijackthis.
Agradecia que alguem ajudasse porque ja tou a dar em doido com isto... :S :S
PS-Fiz o scan com a dita janela com a msg aberta.

Reinicia e ve se o problema continua....

aparentemente tudo em ordem :P


meu obgd mesmo. :)

ja agora era o ke? (ignorancia eu sei mas prontos...)

Tratava-se de um DLL que estava a ser carregado, devido ao seu nome "estranho", fiz uma pesquisa pela net e verifiquei que existiam registos de que se tratava de um ficheiro malicioso.

Se tiveres curiosidade em verificar o ficheiro, podes ir a www.virustotal.com, e fazes o upload desse ficheiros, e vês quais os antivírus que o detectam e qual a sua designação.

Podes (e deves) também apagar esse ficheiro. Está localizado em C:\WINDOWS\odunbexu.dll

Tks!

Procurei o DLL mas nao existe. Tipo, se calhar qd fez o fix apagou o dito. nao sei :S


seja como for tudo em ordem a 100% :)

tks
