How Do I Start Using Windows Defender & How Good Is It?

I have Comcast too, and have never really cared much for their version of Norton. With all the things going on lately at Symantec I am not surprised at all that Norton is no longer free with Comcast. When you remove Norton, Defender should turn on or at the most it may ask you for a few clicks in the Security Center to get it going. It is best to use the dedicated Norton Removal Tool to remove Norton completely. Defender will not turn on if you have any residual Norton files left behind.

I have experimented with a few third party AVs and always came back to Defender. It works very well and ranks right up there with the big gun popular paid AVs as far as protection and usability/system impact goes. My system runs quick and light, smooth as glass with Windows Security. I also use the Bitdefender Trafficlight extension and Adblock Plus, both work great together with Defender and that is all I need.

You can search online for Andy Ful's Configuredefender tool to harden and enhance Defender. I have never had a need for it personally. There are some tweaks and adjustments you can make to Defender now to set it how you want for PUP detection, Controlled Folder Access/Ransomware, Tamper Protection and other features. It also works in conjunction with Smartscreen. What I like best is how Defender is baked into Windows and does not interfere with anything in the OS.
