My PC was attacked by dangerous infection called ACAD/Medre.A last night when i downloaded free application from Internet. After my PC start working weirdly and i get error message time to time. Not only this some of my important apps start responding slow. At last i decide to run my security software to remove this threat. But even after dong that i am getting issues. Is the security software not working? How can i completely remove ACAD/Medre.A from my PC?…
