[Resolvido!]  Não consigo instalar AntiVirus!

Oi, tem uns 3 dias eu desinstalei o Avast pq meu pc tava muito lento e ele sempre alertava sobre um mesmo arquivo, eu mandava pra quarentena, limpava, mas depois voltava a alertar. Daí que estou tentando instalar outro antivirus e não dá, já tentei quase todos!!

p.s.: queria pedir desculpas pq abri um tópico há um tempo atras enão voltei pra ver a resposta, na verdade tive que chamar um tecnico, tava muito desesperada! Dessa vez, vou esperar, ok?! Obrigada!
