[Arquivado] &nbspAnálise de Log HijackThis

Boa tarde pessoal,

O PC possuia apenas 128Mb, substituí por dois "pentes" de 512Mb que já funcionava em outro PC, estava lento demais, com travamentos inexplicados.

Gostaria que analisassem o Log do HijackThis para me informar se o winXP está "limpo" ou é possível melhorar algo.

Log:
