My computer (acer extensa 5635ZG) with windows 7 (x86) in the last 2/3 weeks became more and more slow, showing pop up and programs closing unexpectedly. I ran the antivirus and appeared some trojans, virus and some other "things" I can't recall the name. I couldn't quarantine or delete because the license had expired so I decided to unistall the antivirus and install another one. I unistalled it and when I was intalling the other antivirus, the computer froze somewhere in the installation and I turned it off.
Now windows won't start again, I tried all the options that appear: safe mode, start windows normally and startup repair (recommended).
In startup repair I can get to the command prompt, since other options won't take me anywhere.
I read the preparation guide and decided to follow it. I used the dds.com tool but I couldn't get the dds.txt, it was only displayed the attach.txt, I saved it. I decided to use Farbar Recovery Scan Tool and I got a txt file that follows:
