How do I obtain a new version of Mozilla, one free of "malicious" malware?
My system security warns me of "Maicious Malware" each time I attempt using Mozilla. Each time I upload Mozilla, McAfee warns me there is malicious malware attached. I must then resort to use of an alternative browser. This malware is monitoring both incoming and outgoing connectivity.

When Firefox is downloaded directly from Mozilla you aren't going to get any Malware 'tagging along for the ride'.

As far as a McAfee warning like that; I don't trust McAfee to make such judgement.
