Possível tentativa de invasão

Boa noite, descobri o site através de pesquisas na net e gostaria de saber se vocês podem me ajudar. Olhando o log do meu roteador percebi que este marcava algumas tentativas de IP spoofing. Devo me preocupar? Como bloquear isso?

Vale dizer que ja rodei o Nod32 online, tenho instalado o Norton internet security e tbm ja rodei o Spyware Doctor.
Maquina com Windows 8.
segue copia do log:

Olá Alex!

Desculpe-nos pela demora. Crie uma pasta própria (como por exemplo C:\Arquivos de Programas\HijackThis).

Faça o download do [Tens de ter uma conta e sessão iniciada para poderes visualizar este link] e no momento de salvá-lo escolha a opção de salvá-lo nesta pasta que você acabou de criar e descompacte o hijackthis.zip dentro dela.

Dê um duplo clique no instalador do Hijackthis > clique na opção I Accept.

Clique no botão: Do a system scan and save a logfile. Depois será aberta uma tela com o log, então é só selecionar este Log (Clique no menu: Editar » Selecionar Tudo), depois disso volte novamente no menu: Editar » e clique na opção: Copiar).

Depois disso é só voltar aqui no fórum e postar este log do Hijackthis para que ele possa ser analisado.

Ficamos no aguardo de sua resposta.

Obrigado pela resposta. Acredito que consegui resolver o problema alterando a senha do roteador e o seu nome, visto que as mensagens acabaram. Mas não posso afirmar com clareza. De qualquer forma se copia do log do Hijack.
Obrigado pela atenção.

Sim, esta providência é muito útil neste caso.
