Windows Defender for Windows 10

How effective is the Windows Defender that comes with Windows 10?  Is it good enough to use?  Or would you advise using a for-pay antivirus and antimalware?

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Opinions on antivirus are as broad ranging as they come. Windows defender does not score as highly as some others, but it was designed with a different mindset. Some antivirus tests throw hundreds of viruses to see which get caught, and many of the viruses tested aren't in "the wild." AV scanners that catch them test higher, but that doesn't necessarily speak to real world effectiveness.

MS has designed defender to not bog down resources and to try and effectively catch current threats. It is not designed to beat scores or be comprehensive.

Some prefer comprehensive. Others prefer lightweight. Whether that trade-off is worth it is up to you.

Windows 10 Defender works, but it is not the strongest protection. I use Symantec Endpoint Protection which works very well in Windows 10 and does not bog down the machine at all. SEP turns Defender off and provides its own protection. I use SEP as it think it provides better protection than just Defender.

Of course, exercising common sense and educating clients is the best overall protection. Not getting malware in the first instance is superior to cleaning up afterward.
Defender works well, But I always prefer using Panda Antivirus, as that in my point of view is the best one available. The free version is perfect, you only need to pay for it if you are using it in a business. For personal use I never recommend getting a non free AV tool, as they are in no way better than the free versions. The signatures they use are the same for both.

One thing that is very important, is never to use symantec (norton) products. They are absolute crap (and you even have to pay for them)!

Symantec Corporate products are very good, not crap and score well in Anti Virus comparisons. I am referring to the newest products and NOT the consumer products (Norton) I do not use the latter.
I have never seen any good product from symantec, except the one that removes symante crapware. They tend to buy up other companies that make good software, then they create bloat- and crapware out of the products those companies used to make. There was never any improvement in those products.

The AntiVirus comparisons themselves are very often biased and shouldn't be taken seriously. They are also just a snapshot of the moment.

I just cleaned up a Windows 7 machine with Symantec Endpoint (cleaned up all viruses) followed by Malwarebytes (cleaned up all malware) and the machine works fine. I am happy with the results.

Most likely you and I have just had different experiences and I have no issue with this.

As I said...opinions on AV are as broad ranging as they come. Might as well ask about politics or religion.
I agree with Cliff in all he wrote.
Additionally, I recommend not to rely on AV at all (no matter how effective) but to use software restriction policies or applocker instead.
