Protection
If you must use IIS
- Keep it up to the latest patch (see MS01-044) on a clean system
- The IIS Cumulative Patch does not clean your system of Code Red II backdoors
If you use Internet Explorer
- Secure against MIME auto-execution
- IE 5.01 requires patch (MS01-020)
- IE 5.5 SP2 and IE 6.0 are already immune
