]my pc has Windows build 10586, after you install Freedom Scientific JAWS 16 and Freedom Scientific MAGIC 13.
when I try to start a virtual machine, I get the following errors:

Donde esta la log, por favor?

Please zip and post the log mentioned in the last screenshot, and we'll see what we can do.

According to a web search, "Freedom Scientific JAWS 16" is screen reading software for math expressions, and MAGIC 13 is screen magnification software. Both are likely to have injecting DLLs, which if not properly security-signed by the manufacturer, will not allow Virtualbox to boot. See the ponderous tome at the top of the Windows Hosts forum about Hardened Security.

Here's a tl;dr version:

Basically, some programs can use a normal Windows function to inject themselves into other programs to allow cross functionality. This is what causes a theme crack to work in all the windows that appear, or Antivirus to read running programs, or online-meeting software to put into the windows their extra buttons, etc. Malware can do this too, and with a super-powerful program like Virtualbox punching holes in the security levels to get more than one OS to run on a PC at once, bad things can happen.

So Virtualbox checks to see if the program that wants to inject into Virtualbox is signed with an authenticity certificate. If it's not, Virtualbox won't start.

Some program distributors haven't signed their programs. If they haven't you need to ask them to distribute a signed version. Which ones to ask? Look in the logs for "supR3HardenedError" or "error" or "reject", the end of the line is the unsigned program.

Yep, looks to me like it's the Freedom Scientific stuff. Taking a look for the word "reject" I see the log shows rejects on "C:\Program Files\Freedom Scientific\Shared\FSMonitor\1.0\FsMonitor.dll"

Could be they just forgot to sign it, but you'll have to get them to do so if you want to run their programs and Virtualbox on the same PC.
