The Mac OS X Flashback Trojan virus seems to have a lot of people worried lately, and for a good reason. The Flashback Trojan virus comes in many forms and has been known to upload personal data to a remote server. To make matters worse a Russian antivirus company that goes by the name of Dr. Web recently concluded that there were over 600,000 Mac computers infected with the Flashback Trojan virus.
If you are worried that you are infected with the Flashback Trojan virus then you will be glad to know Gizmodo pointed out some easy to follow instructions for checking to see if you are infected, and also how to get clean if you are.
How To Check/Remove Flashback Trojan (Mac)

Step 2) – Next you will need to type in the following command:

Step 3) – After typing in the command you will need to take note of the value, DYLD_INSERT_LIBRARIES. You should also receive the following error message:
