I recently posted one of the trillions of discussions regarding the Flashback virus here:
I confirmed that my 10.5.8 Leopard run Mac Pro did indeed have the virus. All the behaviors were there: Power PC/Rosetta run apps were crashing on start up and the Terminal utility showed the presence of the dreaded DYLD_INSERT_LIBRARIES. After that, I was out of town for about a week and the Mac Pro was shut down for that period and upon my return, I was to wipe and reinstall to start fresh. While away, I read some more articles about the virus and some remedies and removal techniques, so I returned home hopeful that the wipe and reinstall would not be necessary.
But.... when I fired up the Mac Pro today after a week of being shut down, it seems the virus was gone. ??? Is this possible? I entered the following lines in Terminal and got 'does not exist' on all of them!
defaults read ~/.MacOSX/environment DYLD_INSERT_LIBRARIES
defaults read /Applications/Safari.app/Contents/Info LSEnvironment
defaults read /Applications/Firefox.app/Contents/Info LSEnvironment
My older Power PC/Rosetta run apps started up fine with no crashes. I also turned off Java in Safari preferences. So the question is, what to do now? Should I immediately update to 10.6 Snow Leopard (I have too many Rosetta run apps right now to shift to Lion) and get all native softwares up to date? I would imagine that Snow Leopard would be safer at this point than my old Leopard. Should I install a Mac virus protection app as well? Should I also keep Java OFF at all times?
