Hi everyone. I was trying to download an application for iTunes Library syncing, so I went on Rapidshare search and typed in the name of the program (tuneranger). One result came up. I downloaded it and extracted the content. The app was called 'blind.app'. I don't know why I opened it but I did. It appeared on the dock for like 2 seconds and then disappeared. Then I realized it could be a virus so I deleted all that I had downloaded. However, every time I open a folder now, there is a file called ".DS_Store". It is in every single folder of my computer. Any help is welcome. Thank you very much in advance. Yani.
