Obrigado, já tinha pesquisado antes e vi uma série de sites dizendo que era virus, e desconfiei porque aquele ficheiro estava a consumir muitos recursos, mas coloquei o log no site do hijackthis e também deu limpo.
Muito obrigado pela atenção. Valeu.

tu tinhas/tens algum ficheiro de nome csrrs.exe activo em memória?

não confundas com csrss.exe....
que é o serviço que suporta o Microsoft Client/Server Runtime Server Subsystem.....
resumindo trata do tratamento dos comandos de origem gráfica para o (ou do) Kernel ou serviços associados...

o primeiro, csrrs.exe, é um cavalo e troia e pode vir disfarçado com diversos nomes... geralmente descrrega um conjunto de dll associadas...
acho que no link encontras uma lista deles...
