re: McAfee downloaded anti-virus without my permission!
Yep... Likely it piggybacked on an installer if you had previously removed it from your system.
In general - it is best to avoid "download havens" and sites like CNet, Softpedia, et al and even many blog sites. Typing "free" in your search string often gets you these places as a result.
Yes it is free and yes it (probably) is the program you are seeking, but these places typically make money by "bundling" other "offers" into the installer. It is the #1 way in which the average consumer adds bloat to their system and cause it to slow down.
Do your research on what program or utility you want and then seek out the publisher's website for your download. "Easy" has a hidden cost most times.
