Virus? Spyware?

Boas,

Adquiri recentemente uma máquina nova. Tenho 2 discos sendo que um deles está partilhado, Disco C (sistema) e disco X (Trabalhos). Neste disco X aparecem-m regularmente pastas tipo "/34195eee2d57a1a8289c1ecdef", "/8893876321193f4be2", "/c76ca08b2dea608a7f99206f628f5ce1", etc...

Ontem dentro dessas pastas aparecia somente um ficheiro executável: "[FONT=Verdana, Arial, Helvetica]mrtstub.exe"

Hoje dentro das pastas encontro uma segunda pasta de nome "/update" e dentro desta o ficheiro "update.exe" e ficheiros "*.dll"

Noto que estas pastas surgem quando faço um update do windows, ou por exemplo, quando corri o Onecare Live do Windows, ou ainda, quando corri uma ferramenta de remoção de malware da Microsoft.

Alguém sabe o que isto é?

Obrigado

Neste momento tenho instalado o Antivirus NOD32 2.7 e firewall do Windows.

Tirando o facto de consumir bastante a máquina, tenho muito boas experiencias com o Norton. Anos sem pinta de MalWare e Virus. Estou mesmo a pensar em instalar novamente correndo o risco de perder um pouco da performance!!!

Obrigado.
