Does Windows defender on Win 8 replace Anti-virus software

Just built a Win 8 Pro for our company President and need to know if it also requires Anti-virus in addition to Defender?

Windows Defender provides only a baseline support. It's not as good as other security softwares. You may like to download and install a good (free) antivirus software. Starting with a: Avast, AVG, Avira, etc. I recommend Avira.

Once a third-party antivirus program is installed, Windows Defender will turn itself off. And once this program is uninstalled, it will turn itself on. Therefore the PC will always be protected.

I have only Microsoft Essentials on my Win 7 computers at home.  Should I have something stronger?

Windows Defender initially an anti-spyware program, however, it is upgraded to an antivirus program. You stick with Windows Defender if you want too. When you go to a third party antivirus they are just more experience in that software area.


Microsoft Security Essential is okay....

jrsitman, Most definitely. Install a third-party antivirus program. You will not regret it.

Sorry, but how would one be able to answer your requirements, if there are none defined?
What do you need?

Defender updates itself regularly, it runs as an on access guard in the background, it protects itself against tampering - what more do you need?
No, it might not have the best test results. No again, it won't be able to block USB devices and no, it may not be able to follow as many policies as Kaspersky does in terms of reporting and...

But what do YOU need? :)

Thanks for all the comments and advice.   You all pointed me in the right direction.  I'll go with a 3rd party.  Probably Avira.

What do you expect Avira to do for you that Defender cannot, if I may ask?

@McKnife

I was influenced by the reviews I read and your comments "it might not have the best results"

Ok ok... It's quite useless, but let me tell you that much: people modify old viruses, so that no (0) scanners do find them. Yes, they simply take an old one, modify it and upload it to virustotal.com - if it still gets detected, they again modify it and upload it until it goes through undetected.

AV software is some small part of a security concept. The MS one integrates very good with windows, please consider that. If someone isn't cautious, no scanner will save him. And if scanner A knows 90% and B only 78%, so what? Both will get infected sooner (B) or later (A) due to their users' behavior. I am a long-term admin of McAfee and Kaspersky corporate products. If your systems are configured correctly, those products will only do one thing: eat resources. Ah, and cost money and nerves.

McKnife, I gave no reasons. Just pointed out some test results. Cheers. :-)

About antivirus software: We all have opinions. It's (the choice of software) rather subjective and depends on one's surfing habits and individual preferences.
