Windows 10: Viruses, need a lot of help

So my partner had downloaded some things, unknowingly things that were harmful. There is now something attacking our computer. It pops up with a text box that says “cmdexe” on the top of it, and also our chrome keeps getting this extension that says “Phone” and that extension being there suddenly takes us to Microsoft bing when we make a search. But the problem is, when i search for viruses both on the computer and Chrome, nothing shows up. Please help asap.

Lots Of Daily Spam Emails

Yes, I do appreciate your feedback and help. You're helping suggest ways on blocking all that, which is Step 1; we gotta take the first step. But the way that I'm looking at it is why stay stuck in Step 1 instead of moving on to Step 2? Step 2 is having a response to all this. So Step 1 is to block the non-sense, then Step 2 is to take down the source, if you see what I mean. I wanna apply Step 2. Let's move forward in the whole process, yah? =)

Cool thanks Momma!

 

Why did the startup window get cleared?

I didn't missed any step, the list was gone and gone , even after using lot of programs the programs were not listed in that list.
