Hook up an external USB keyboard and mouse (any will do) to regain some control.
If you have another Mac (and i'm pretty sure you do as you cloned), hook them up in Target Mode so you can Disk Utility on the hard drive and repair it. Here's how:
Connect the two computers with a FireWire or Thunderbolt cable. Start up the computer to be used as a disk in target disk mode: If the computer is off, start it up while holding down the T key. If the computer is on, choose Apple menu > System Preferences, click Startup Disk, and then click Target Disk Mode.
Cloning used to be great but it fails on a new drive because the Repair Partition does not get installed.
At this point it would be better to back up your user data to an external drive, then wipe and start over.
Keep in mind that if you do find infections, most likely it has spread to any back up drives so they will need to cleaned too.
If possible it would be better to just wipe the drive with the backup of your old data.
A couple of ways to do it. From Target mode I would reformat the drive using the "write zeros" option to map out any bad blocks, then format OS X Extended.
Now you either install a system in Target Mode or do a clean internet install.
You can now see if it's working with a clean, correctly formatted drive or see if you have other problems.
If it's working OK, use migration assistant to move your data.
But before doing that:
You are not on Santas' naughty list, you are on his very naughty list. Downloading torrents is one of the very fastest ways I know of to infect a Mac. I would give you 10 to 1 odds you have brought home a social viral disease and given it to your spouse. bad boy ;-(
So before starting anything you need to try to clean that up. Do it first on your working Mac. There are some free ones at the App store, so start with those and find out how bad it might be on your working Mac,
If you find infections there I would seriously consider getting good anti-virus, anti-plishing protection. I like Symantecs Endpoint Protection: https://www.symantec.com/pages.jsp?id=ca...
Others on the site may have other recommendations on anti-virus programs.
Once you know the working Mac is clean then run it one the other one in Target Mode.
