That's odd -- the links work OK for me.
I'm not sure why it would be so hard to uninstall the OEM McAfee software on a new Dell box.
Have you tried running the removal tool in Windows Safe Mode.
Perhaps this has something to do with it?

Yes, Dell support quality has waxed and waned over the years.
The story you relate sounds more like some sort of scam, as I've never been shunted to a 3rd-party support provider, let alone one that found many unrelated issues on the computer. That seems pretty suspicious.
My recent contact was to an offshore support center, but it was Dell Premium Warranty Support. The agent spoke perfect English, let me drive on the remote session, had a logical approach to the hardware issue, and resolved the hardware problem efficiently and correctly. YMMV, of course.
But, again, if it is a new system, under warranty, with OEM McAfee software installed at the factory by Dell, then it would seem logical to contact either Dell or McAfee, if standard troubleshooting isn't working?
I am just a home user. So perhaps the more expert folks here will have some other ideas.
Sorry I couldn't help.
Please do let us know how it goes.
