rather than uploading them again into this space in addition to the other public places, please search the KC - links to the guides can be found here: https://www.google.com/search?q=mcafee+web+gateway+7.4.1+product+guide
For donwloads, are you able to access : https://contentsecurity.mcafee.com/?
If not please send a mail to firstname.lastname@example.org in order to get your account set up.
the mose recent documentation can be found at https://contentsecurity.mcafee.com, which is a different server. You should try that location as Michael mentioned. Posting the guides again does not seem very useful as no one will take care for updating the documentation. Thats why it is usually managed at a central location.
