[Resolvido!] Anti-vírus acusa vírus na memória RAM

Olá,

Possuo o anti-vírus Avast e ele já deu o alerta de vírus na memória RAM umas 3 vezes. Ele solicita que eu reinicie o computador para que seja feito um escaneamento no boot.

Nas duas primeiras vezes, escaneando no boot, ele não achou nada, já na terceira apareceu e eu mandei excluir, mas quando subiu o windows deu o alerta novamente.

O Avast acusa os arquivos rdtcgn.sys e tyzsoujf.sys na pasta Windows/System32/Drivers/

Depois que começou a dar esses alertas, a internet fica lenta em alguns momentos.
