Best Antivirus Software of 2017

Windows 10 comes equipped with two apps Windows Defender and Windows Firewall that do a great job fighting against viruses and other types of malware. Many users will say Defender and Firewall are all they need, while others want a third-party option handling their PC's security.

If you're interested in taking your security to another level, check out this roundup of the best antivirus software available in 2017.

Bitdefender Antivirus Plus 2017

Bitdefender Antivirus Plus provides amazing protection against system-crippling viruses and other annoying malware.
Its robust protection is built on the data gathered from over 500 million Bitdefender users algorithms measure the data to uncover unknown threats and to discover new threats just now hitting the internet.Chosen as the best basic antivirus by Tom's Guide and as Top Ten Review's first choice overall choice, it's clear you're getting your money's worth.

Bitdefender Internet Security 2017

Bitdefender's Internet Security 2017 is like the bigger, stronger sibling of their Antivirus Plus package.

Webroot SecureAnywhere AntiVirus

Webroot SecureAnywhere AntiVirus is an interesting package its signature database is stored in the cloud, which means it only takes up about 2MB of space on your hard drive and doesn't require constant updates. It also only takes up about 4MB of RAM during system idle, which is especially important for those of you that don't have much RAM to spare.
Here's how the cloud-based Webroot SecureAnywhere AntiVirus works: new files and programs are scanned and their signature is sent to the cloud to be analyzed. In the meantime, the file or program in question is kept in a quarantine state with some of its function unusable. When Webroot determines the file or program to not be malicious, the quarantine state is lifted. If you don't have internet access, programs and files you've previously accessed on your PC remain usable, but new ones will be placed in the quarantine state until you reconnect to the internet.

Norton Security Standard

Norton has been around for a long time, so it has had time to make plenty of friends and plenty of enemies — many people swear by it, many people hate it. In a review conducted by Tom's Guide, malware protection was praised while system impact was listed as a concern. Likewise, Top Ten Reviews gave it an almost perfect rating.
Like most big security companies, there are multiple options to choose from the simplest, Norton Antivirus Basic, costs only about $15 and was named an Editors' Choice by PCMag. The step up, though, comes with a firewall, great customer support, and a few other extras that make it worth the $40 per year.

Avast Pro Antivirus

Avast has a great free option that many people take advantage of, but this step up into their paid selections is perfect for anyone who wants a few more tools when it comes to protecting their PC.
In their review, PCMag identified exactly why you might want to upgrade:
''To the cornucopia of bonus features found in its free counterpart, it adds protection against DNS poisoning and a sandbox for running iffy programs safely.''
While this might not be enough of a reason for many people to buy this $50 yearly subscription, it's great for anyone who trusts the Avast name.

Trend Micro Antivirus+


Trend Micro's Antivirus+ option is one of the cheaper selections on our list at $20 for a yearly subscription, but that doesn't mean it isn't a decent antivirus. Testing conducted by independent lab AV-Test saw Trend Micro's protection work perfectly.
A review by Tom's Guide confirmed the lab's protection testing:
''Trend Micro's security programs provide most of the protective services you'll need, are fast to scan and provide a near-perfect shield against malware.''
There are differing opinions about how this AV affects the performance of a PC, but overall it's no worse than the average. If it's a powerful antivirus you need but don't want to shell out as much money, Trend Micro Antivirus+ might be your best option.

McAfee AntiVirus Plus

Like Norton, McAfee has been around for a long time, and many people have already formed an opinion. Regardless of whether or not you like McAfee, one thing is certain: a $55 one-year subscription provides protection on an unlimited amount of devices, including Android, macOS, and iOS. That's a pretty sweet deal, but keep in mind that not all features are found on all devices.
What you get on PC is great malware protection, a simple user interface, wonderful tech support, and a firewall. Chosen as an Editors' Choice by PCMag.

eCPM -- what exactly is that?

eCPM is a bit of industry shorthand that seems here to stay. You've seen it listed in your AdSense reports; it means, "effective cost per thousand impressions." So how is eCPM calculated, you ask?

eCPM is calculated by dividing total earnings by total number of impressions in thousands. It is a great performance measure for your various ad units, so when experimenting, you can use eCPM to compare your results.


But what if your site doesn't receive enough impressions to have a large sample size? Even for smaller sites, eCPM can be a useful statistic to track ad performance.

For example, let's imagine we have two custom channels named 'Blue Skyscrapers' and 'Red Rectangles', respectively, which reflect the types of ad formats we're testing on our site. During our test, the 'Blue Skyscrapers' channel receives 370 page impressions and $1.48 in total earnings. The 'Red Rectangles' channel receives 187 page impressions and $0.97 in earnings over the same period. To make these figures more comparable we calculate eCPM -- i.e., the estimated earnings for every 1,000 impressions received. We find that eCPM for blue skyscrapers is $4.00 while the eCPM for red rectangles is $5.18.

This means if we received 1,000 impressions of blue skyscrapers, we would earn roughly $4.00. But for 1,000 impressions of red rectangles, we would earn about $5.18. Therefore, assuming that our sample size is large enough, it is to our advantage to switch to red rectangles throughout our site because they generate more revenue per impression.

New Facebook feature makes it easier to creep on your friends


The social media company announced Monday that it's adding a Live Location feature into its Messenger app, designed to help bring people together when they might not know how far apart they are.

Facebook is making it easier to answer the question, "Hey buddy, where are you?"

The Messenger app already lets you send your current location to a friend, but the new feature expands on that by updating your spot on a map as you move. The feature will remain turned on for an hour, and friends receiving the location will also see an estimate of how long it would take to get to the person's location by car.

The feature, which Facebook said is rolling out globally to iOS and Android, will let you send your current location to one or more friends at a time.

Cortana is now available on the Android lock screen



Microsoft has been trying to force android and iOS users to use more offten her personal assistant CORTANA, and the latest addition is a new lock screen option for Android today. While the feature has been in beta since January, it’s rolling out to everyone today.
Microsoft isn’t replacing existing lock screens with Cortana, but you’ll be able to access the digital assistant simply by swiping left or right on a floating logo, making it just as quick to access as Google’s own options.
Alongside the lock screen integration, the Cortana home section of Android is getting refreshed today with information like calendar events, weather, and travel time to work displayed as soon as the app is launched.
Microsoft is also launching Cortana for iOS and Android in Australia today, making it the third country the mobile app is available alongside the US and UK.
