My computer has been acting very strange lately. I know Macs aren't prone to viruses, so I may or may not have one. There is also evidence of some tampering as if I've been hacked.
Regardless, I have not backed up via TimeMachine for about a year. Should I run a backup to my external hard drive or do I risk infecting it also and thus all my backups and other files on the external hard drive?
MacBook, Mac OS X (10.5.8)

Flashback - Detect and remove the uprising Mac OS X Trojan...

In order to avoid detection, the installer will first look for the presence of some antivirus tools and other utilities that might be present on a power user's system, which according to F-Secure include the following:
/Library/Little Snitch
/Developer/Applications/Xcode.app/Contents/MacOS/Xcode
/Applications/VirusBarrier X6.app
/Applications/iAntiVirus/iAntiVirus.app
/Applications/avast!.app
/Applications/ClamXav.app
/Applications/HTTPScoop.app
/Applications/Packet Peeper.app
If these tools are found, then the malware deletes itself in an attempt to prevent detection by those who have the means and capability to do so. Many malware programs use this behavior, as was seen in others such as the Tsunami malware bot.
