.I wouldn't worry about it, assuming the BIOS update came from Toshiba. You didn't say where you downloaded it from. 
I have a Toshiba laptop myself, so I know how their pre-installed software can tell you that you need to do these things. You didn't mention any problems, so I can only assume you aren't having any. Just be sure you have good antivirus software and keep it up to date.

You should also give consideration to how you're going to back your system up so when the inevitable malfunction of one sort or another hits, you're not hit with a bigger disaster than need be. I have to tell you that before I read your post, I'd never heard of Insydeflash. I did a Google search to find out what it does. If you have questions about it, you could ask Toshiba. You could do a full system scan with your antivirus program, if you suspect it's not on the up and up. My experience with Toshiba has been pretty good - far from perfect, but among the better ones. Since your computer is new, it's under warranty, but if you get a software problem, that warranty won't help, so be careful and back your system up regularly!
Greetings, all. I had a very similar experience on a new Dell Inspiron 17 laptop running Windows 8. I got an alert from Dell about a necessary upgrade to the BIOS file, and clicked on it - it ran this Insydeflash protocol, and now my Firefox browser refreshes every 20 seconds or so, interrupting typing. I've got a McAfee antivirus that came with the machine, and it didn't flag the file when I ran it, but I'm now at the point where this is totally frustrating. I tried resetting Firefox and that worked the first time, but it didn't work this morning.
Any suggestions on how to resolve this are welcome. You don't know how long of a period between when your laptop was built and you purchased. Sometimes even though you have a new PC there could be updates out there. If you are computer savvy I would look on the Toshiba site under your model and the driver download section and look for the BIOS. It will contain the version and check what your machine has.

I believe it the version you have already it will say if you try to flash the same version. If your not a techie Toshiba support will walk you through it.
