Reclaiming an Infected Computer

Problem

My client’s business laptop was infected with malware. It was required that the documents were recovered and that the laptop was cured.

Solution

Fortunately my client possessed a recovery disk that allowed for a fresh Windows XP installation. So rudimentarily, all I had to do was recover all of her work documents; conveniently, the documents were all located on the desktop.

Let’s start with back-ups

I always make a back-up before working on a PC. This assures that any wrongdoings can be reversed. I used a free utility called “Clonezilla”. Clonezilla allowed me to make an image of the hard-drive and create a back-up onto an external hard-drive.

Recovering data

I used Knoppix with F-PROT (both of which are free). Knoppix is a Live Linux CD, whereas F-PROT is a virus scanner. I used the Knoppix / F-PROT combination to: retrieve my client’s documents, create a back-up on a flash-drive, and scan the very files I backed up.

Wrapping up with re-installation & recovery

By using the recovery disk that came with my client’s laptop, I formatted the hard-drive and re-installed Windows XP. After installation, I copied the recovered documents from the flash-drive to the desktop (local hard-drive) as it was before.
