Windows Messenger toda hora pede pra atualizar.

Estou ficando desconfiado, não uso o Windows Messenger, desinstalei ele do PC e mesmo assim pede para atualizar, alguém sabe se pode se tratar de vírus?
Usei um programa ai pra verificar os arquivos pelo tal de Hijack.
Agradeço ajuda, abraços povão!!!! 8)
