* Enhanced Virus Protection can be enabled by certain operating systems, including the current versions of Microsoft® Windows®, Linux®, Solaris™, and BSD Unix. After properly installing the appropriate operating system release, users must enable the protection of their applications and associated files from buffer overrun attacks. Consult your OS documentation for information on enabling EVP. Contact your application software vendor for information regarding use of the application in conjunction with EVP. AMD strongly recommends that users continue to include third- party antivirus software as part of their security strategy.
