Check for the Flashback Trojan in Mac OS X

by OSXDaily


You can check if your Mac is infected with Flashback Trojan or not with the following Terminal commands.

Launch Terminal (/Applications/Utilities/) and enter the following commands:

defaults read /Applications/ LSEnvironment


defaults read ~/.MacOSX/environment DYLD_INSERT_LIBRARIES

If your machine answer is:

“The domain/default pair of (/Applications/, LSEnvironment) does not exist


“The domain/default pair of (/Users/joe/.MacOSX/environment, DYLD_INSERT_LIBRARIES) does not exist

then your Mac is clear.
