I've noticed quite a few questions about people thinking that they might have a virus on OS X. Everyone should know that, so far, there are absolutely NO viruses for OS X. There are a few hundred for OS 9, but NONE for OS X.

Strange things occuring with applications are usually the fault of that application.

There are virus scanners for OS X such as Virex and Norton but they are only scanning for Windows viruses and the old OS 9 viruses, so there is not much use for them unless you want to take it upon yourself to protect PCs if you forward strange emails to people.
