I'm on W10 too and use only Windows Defender now that it scores well.
Kapersky lost over how they break System Restore. Also, never run more than one AV. If I want to have a second opinion scan, I use Grif's list at http://www.cnet.com/forums/discussions/how-to-remove-pup-option-603542/#post-f742c795-5881-433b-a29b-6d758efe5cd3
Now at 2 years using just that (and a few browser addins) I have yet to find a virus, trojan, malware or such.
Here's how I beef up the Browsers.
1. Ublock Origin and if not supported by the browser, Adblock+
2. Web Of Trust. If WOT is other than Green or clear, I don't go there.
3. I use NINITE.COM! If you don't know why, google ninite up.
Hope this helps.
I'm running Windows 10 Pro. I am currently running Bitdefender Internet Security (Trial) and have a free license for Kaspersky Small Business Security (I think) from my dad's work.
I was talking to a computer tech and he suggested I run Windows Defender whilst periodically running Malware Bytes and Spybot Search & Destroy manually in conjunction with Kaspersky's Rescue Disk; he told me that both Kaspersky and Bitdefender are extremely resource-intensive and would not recommend using them.
Does anyone agree, or disagree?
