I spent hours trying every suggestion I found in these forums and none worked.
Until I found this one (from
http://ianlunn.co.uk/articles/quickly-showhide-hidden-files-mac-os-x-mavericks/)
- Open Terminal found in Finder > Applications > Utilities
- In Terminal, paste the following: defaults write com.apple.finder AppleShowAllFiles YES
- Press return
- Hold the ‘Option/alt’ key, then right click on the Finder icon in the dock and click Relaunch.
At this point you can see every hidden file on your computer, including the hidden files in your USB.
That was the only way I could find all my original files, and then copy them to my desktop.
After that, go back to Terminal to hide the files again, following the same steps but replace the Terminal command with:
- In Terminal, paste: defaults write com.apple.finder AppleShowAllFiles NO
Once I assured I had all my files saved in my computer, I formatted the usb and got rid of the virus as well...
Hope it helps!
