Dell Inspiron 15 laptop may be infected with malware

A few days ago on Facebook I clicked on a story in my news feed and I was IMMEDIATELY kicked off and FB's warning message said my Dell Inspiron 15 laptop my not be safe and it may be infected w/malware.

I tried using Facebook on my smart phone. At first it worked; but after a few minutes it gave me the same warning message. I had to download their F-Secure Online Scanner before I could log back into FB on my phone and on my laptop.

Now I'm logged in; but the laptop is running super slow; it switches from one thing to the next; when I click on the shortcut to open the SUPER AntiSpyware, it opens CCleaner instead. This was 5 days ago and it's not improving even after running SUPER AntiSpyware, CCleaner and Malwarebytes Anti-Malware; all of these are the free download versions. My phone is acting weird, too, running slowly, etc.

Today I cannot open emails in from my yahoo account on my laptop. I click on them; but they don't open. When I click on a link to open something, it automatically opens a new window without my requesting it.

Help! What can I do to clean my laptop and my Galaxy Note5 Android phone? Thank you!
