It’s a long-established fact that the internet is rife with malware and spyware.

But what about antivirus software?

The main antivirus platforms are Microsoft Windows and Google Chrome.

But many companies are now releasing their own versions.

The main ones are Microsoft’s Windows Defender, Google’s Chrome, and Google’s Antivirus.

But if you don’t have a Windows or Chrome machine, or want a free one, there are a few other options available.

The first is a free, free version of Microsoft’s antivirus called “Windows Defender Pro”.

This is a full-featured anti-malware product that will run on Windows XP, Vista, and Windows 7.

You get full support, and you get access to all the latest security updates.

This is what it looks like.

For those who have an older version of Windows, there’s also a free version called “Microsoft Windows Defender Enterprise Edition” or “Microsoft Enterprise Security” or a “Microsoft Free Security Edition” for those with Windows 7 or Windows 8.

You can also buy a commercial version of the Windows Defender.

Microsoft has been pushing the security features for years, so there are some good reasons for using a free antivivirus that can keep you safe from malicious software.

However, the free version also has a few limitations.

It does not work with Windows 10, and it doesn’t work with some of Microsofts newer operating systems like Windows 10 Mobile.

So it’s important to choose a paid version.

You’ll need to pay for a license that will let you install a paid copy of Microsoft Defender on your computer.

It will be installed on your desktop, and on the mobile devices it will be used on.

You need to make sure you are using the latest version of this paid version of antivirus.

Microsoft recommends upgrading to Windows 10 Professional.

If you want to use a paid Microsoft version of Antivir, you’ll need a Microsoft account.

You’ll need the full version of a paid antivirus for $79.99.

It can be purchased in the Microsoft store.

There are several free antivirs that offer the same functionality.

These are available for Mac and Windows.

You should also be aware that if you use a third-party antivirus solution, like the Google Chrome browser, you’re still installing the software on your machine.

It could make your machine less secure.

The free antiviral programs are also available for other operating systems.

If your antivirus provider offers a free alternative, you can try that.

The next most popular option is called Avast.

It has a very well-known reputation for security and anti-virus features.

It’s also one of the most popular antivirus products out there.

For many, this is the most secure option.

However this is only one of several options available for free.

You will also need to purchase a license from Microsoft.

If that’s not possible, there is also the Avira free antivircreation service that is available for $59.99 per year.
