Backdoor.Flashback.39 is said to be the most dangerous malware that has been developed for the Mac. It turns your machine into a botnet node becoming remote controllable. Most likely purpose will be sending of spam from your machine but it could also involve other activities.

The trojan has so far surfaced mostly in the US (300.000 infected Macs), Canada (90.000) and UK (50.000). But to be on the safe side visit the Kapersky Lab Site http://www.flashbackcheck.com/

Note: Following March 8, 2012 your computer if infected will lose internet connectivity and — if worst comes to worst — be redirected to malicious sites.

The malware scam DNSChanger that has affected numerous computer systems, including Macs, has been at least partly dismantled by the FBI’s Operation Ghost Click program. (But this program will be terminated in March 2012.)

DNSChanger is a Trojan horse that was distributed in many forms, and when installed it actively changes the infected system’s DNS settings to rogue servers that redirect legitimate searches and URLs to malicious Web sites that attempt to steal personal information and generate illegitimate ad revenue for the scammers.
