Protection is on the house

If you were searching the net for a free Internet security package, then might I suggest checking your own back yard first? If your computer is running Windows 8 or later then you'll be surprised to know that you already have a solution installed. It's called Windows Defender. For all the low-tech people out there Microsoft has made the Security Essentials package which is more or less the same thing.

Microsoft Security Essentials

There you go

Microsoft Security Essentials is a real time protection agent and and scanning service for viruses, spyware, rootkits and other buggers that live on the wild Internet. Besides getting live protection, you can also order ad-hoc scans or schedule them in advance. When prepairing scans, you can set file exclusions, process exclusions and default actions. There is also a History screen where you can review items that have been quarantined and allowed following scans. You also get to restore or remove them.

Running Microsoft Security Essentials allows you to participate in the Microsoft Active Protection Service . While connected to MAPS, you will automatically report any unwanted software to Microsoft. THis in turn increases protection for everybody else. You can choose between Basic membership, Advanced membership(where you contribute more) and No, thanks.
