The McAfee website is undergoing difficulties at the moment, please try later.
By the way your profile mentions VirusScan 7, that has been obsolete for many, many years. I will remove that from your profile.
I will also clean up other profile fields which are filled in incorrectly.
To download VSE of any type you need a valid grant (license) number and account. If you are downloading from a 3rd party website then it isn't supported here, it appeared from the various strange URL's on your profile, now removed, that may be the case..
VirusScan Enterprise for Linux version 1.6 reached end of life and support on 15th June. This product is removed from the download site since its no longer supported by McAfee. Instead you can use a newer version of the product.
