Virus in Sun Solaris System

Yes thats right, Virus in Sun Solaris System, But not actually.
Its usually considered that unix based systems are virus free. But that does not mean that they are virus free. At least not if they are part of network sharing resources with window systems.
Today I got a taste of this.
There was a folder in Sun Solaris machine shared with windows server machine. RWX permission given to server application for the folder. Recently we started noting that all of a sudden a large number of files with garbage name.exe or garbage.pif and more, started appearing in the shared folder. We deleted the files and again they appeared. We thought there was a bug in the application somewhere which was creating these files. But after a lot of observation, follow up and all we came to the conclusion that there was Virus ( Sality......) in windows system which was responsible for mysterious appearance of those files.
The actual problem was that we knew that our windows server was infected with virus and even formatted it many times but every time these virus will reappear out of the air. Now problem known, fixed and a LESSON LEARNT.

MORAL OF THE STORY:
Dont believe everything you are thought. A supposedly  secure unix system can still carry virus for other systems without itself being affected.
