Windows 10 Main article: It was released on July 29,and addresses shortcomings in the user interface first introduced with Windows 8. Windows Updates Microsoft developers do a reasonably good job at making Windows operating systems secure before their release.

However, it usually doesn't take very long for hackers to discover security weaknesses in Windows and exploit them to infiltrate networks, steal data and take over or disable systems.

Microsoft developers are getting better at fixing security issues, but hackers are also becoming more adept at finding and exploiting new ones. While hackers are quick to find holes or vulnerabilities in Windows, so are Microsoft developers at plugging and repairing them.

Microsoft accomplishes this through regular updates available to all users of genuine Windows products. Because Microsoft usually releases security updates within a few days of a vulnerability discovery, you can improve your chances of keeping your PC secure by downloading and installing Windows Updates regularly and often.

Better yet, you should consider allowing Windows to download and install updates automatically so you don't forget or wait too long to do so. Accessing and configuring the Windows Update settings is relatively straightforward.

Skilled hackers use viruses, malware and Trojans to gain access to your computer, private documents and data.

Nevertheless, protecting your computer from such attacks is relatively simple as long as you are vigilant. A good anti-virus and anti-malware suite includes real-time monitoring that enables the software to detect and neutralizes malicious software before it can install itself and compromise your computer or data.

However, the detection software is only effective if you keep it updated continuously. Most AV suites have an option that allows the software to download and install definition updates automatically.

Therefore, ensure the automatic update option is active and enabled. If your anti-virus does not offer such a feature, you should strongly consider upgrading to one that does.

Better anti-virus suites also include a hardened firewall component. A firewall is essential to protecting your computer from breaches and intrusions, as it limits access to your computer while connected to the Internet or a network.

For most users, default firewall setting should suffice at keeping your PC's hard drive and data free from prying eyes. However, you should review firewall settings regularly to ensure that crucial and sensitive data is off limits to outside viewers.
