Problem is with CNet's Installer itself, you are prompted to d/l & run it first - before you can get the apps you are interested in, and, BAM ... toolbars & add-ons, extension, etc. across your browsers, etc.

Linux is the answer for me - running it on an "older" desktop on its own drive/partition - fast & easy and no trialware.

Away from that desktop so can't reference the name, but there's an excellent video/audio converter that I use to chop up MP4's across various compatible platforms - it's free & very powerful, does almost it all.
