How to remove the CryptoLocker Ransomware.

There is a new piece of ransomware making the rounds on the internet. It is called CryptoLocker.

For those of you who do not know, ransomware blocks you from using your computer in some way. It then demands payment for the unlocking of your computer.

I have posted the steps for removal below.

Step 1: Get a flash drive that can store at least 32 MB

Step 2: On an uninfected computer, go to http://www.bleepingcomputer.com/download/hitmanpro/ and download the bit version corresponding to the bit type of the uninfected computer.

Step 3: Once the file has been downloaded, insert the flash drive you are going to use.

Step 4: Run the downloaded file.

Step 5: Once you see the start screen of Hitman Pro, click on the little picture of a person preforming a kick at the bottom of the window.

Step 6: You will now see instructions on how to create the Kickstarter Live USB. Click on the flash drive you will be using, then press install kickstart. You will then be presented with a warning that the flash drive will be erased. Click on yes to continue.

Step 7: Once the files have been downloaded and installed onto the flash drive, click the close button and take out the flash drive.

Step 8: Insert the flash drive into the infected computer with the computer turned off. Turn it on and then look for info on how to access the boot menu. If you cannot see any info, keys commonly used for the boot menu are F8, F11, or F12.

Step 9: Restart your computer and start tapping the indicated key. If one key does not work restart the computer and try another key on the above list.

Step 10: Now, select the flash drive with the Kickstart program installed and press enter. Once you see the new screen, press 1.

Step 11: Windows will load normally. After you log in, you will see the ransomware. Wait 15-20 seconds and you will see the Hitman Pro start screen. Click next to start the scanning process.

Step 12: Click No, I only want to perform a one-time scan to check this computer. Then click next.

Step 13: Once Hitman Pro has finished scanning, it will display a list of malware that it found. Click next, and if prompted, choose the 30 day free trial. Hitman Pro will now reboot your computer. When it is rebooted it should be free of the ransomware.
