You know that you need an antivirus program, and that you should be careful when you visit sites that are likely to harbor malware, but do you really know how vulnerable your computer is? It can be difficult to tell, especially if you’re not familiar with how hackers detect and exploit your system. Here are three different top 3 antivirus programs Utilities for 2016.

1.Bitdefender antivirus

Long-time Bitdefender fans will notice some small changes in the main window's appearance. Nothing big, mostly just moving things around. One addition is a large panel with your email address and the label Go to Bitdefender Central. That email address is important. Once you've activated the product on one system, other installations using the same email address are activated automatically. And if you upgrade to one of Bitdefender's suite products, all of your installations upgrade automatically.

2.Kaspersky Anti-Virus 

The product's main window retains the green-and-white color scheme of its predecessor, but the layout is quite different. The previous edition filled the window's four quadrants with big panels labeled Scan, Update, Reports, and Virtual Keyboard. The current edition retains the same division of labor, but the buttons are now smaller, borderless, and horizontally aligned. A large banner across the top reflects current security status. If it's anything but green-for-good, you can click for details, and for instructions on solving the problem.

3.McAfee AntiVirus Plus

McAfee AntiVirus Plus is very capable, and it includes a raft of bonus features. But what pushes it into stardom is the fact that a single subscription lets you install protection on every Windows, Mac OS, Android, and iOS device that you own.
