If you have a virus from iChat, or anywhere else on a Mac, you should notify the world about it as nobody has ever heard of such a thing. There is a Trojan file that can be downloaded by clicking links that may have been sent via iChat. (See links below) You should delete the downloaded file which is often called LatestPictures and remove the apphook.bundle from your account's Library folder... /Library/InputManagers/apphook.bundle Then restart the Mac. After that make sure you never download anything that you do not know what it is and where it is coming from.
There is no version of iChat for Linux.
