Macintosh Java Flashback Trojan Update Procedure OS X 10.6

The problem…and suggestions for fixing it: pre-emptive steps with Apple’s update and/or a diagnosis and infection-deleting process using Unix Terminal to see if you are infected (you need to be very careful fooling around with the unix solution) which is below the [easier] Apple update info that will patch up the problem in Java that lets this happen

Plan “A”

Pre-emptive: After downloading Apple’s Java update, read the info before installing, you should see…

“Java for Mac OS X 10.6 Update 7 delivers improved compatibility, security, and reliability by updating Java SE 6 to 1.6.0_31.

Please quit any web browsers and Java applications before installing this update.

See for more details about this update.

See for information about the security content of this update.”

After running the update…

In Apple menu, open “About this Mac,” then scroll down to “Frameworks”…and open it…

you should see these files updated to either April 6 or today’s date…

Plan “B”

Diagnosis and fix using Unix Terminal – be very careful or get a nerdy friend to assist with this IF YOU OPT TO DO IT THIS WAY…follow the link. The diagnosis is fairly harmless and fun to do. Curious? Want to see if you’re infected? Pre-fix? You will find out if you indeed have been infected or see that you are free of it…Entering commands to repair is another story.

The basic instructions at  F-Secure

I opted to run the diagnosis before and after running Apple’s update. I ran the terminal commands and confirmed I have a clean system…
