I would avoid relying too much on Iobit softwares for protection. They are more useful as system utilities and often detected as PUPs from security softwares. Better use products such as Avast, Avira or Panda.
Your link to the file manager Free Commander is broken. The correct link is freecommander.com > en > summary BTW: I use Free Commander XE every day. It is the best file manager I have found. It is highly configurable, so plan to spend some time making it fit your needs. Edit: I had to hide the actual link because I have not made enough posts to the forums. This rule makes it hard to report a broken link.
I'd add SEDUtil if it has not already been mentioned, for those with Opal 1 or 2 SSC self-encrypting drives Actually, most popular SSDs come with Opal 2 SSC hardware-based AES-256 encryption like Samsung, Crucial, Intel, etc. I do not have the posts needed to link it but it's freeware on GitHub and right now the only freeware out there able to set up drives with the Opal 1 or 2 SSC. It's easy to set up the drive, flash the appropriate little PBA - which is just a tiny live Linux distro - and will fully secure data-at-rest for these drives. It's really quite popular among those looking to utilize the Opal SSC without having to use enterprise-grade software. Hell, I can even upload the PBA I made that looks a bit bitter than just the regular PBA SEDutil uses.
