  • Use a firewall

Using a firewall is like locking the front door to your house—it helps keep intruders (in this case, hackers and malicious software) from getting in. Windows Firewall is included in Windows and is turned on by default, there are other vendors that integrate their local firewall solutions as part of a comprehensive endpoint protection. Symantec, McAfee, and Sophos, just to mention a few companies, provide local firewall solutions as well.

Whether you want stay with Microsoft or use your Antivirus vendor’s firewall is a matter of preference. In my case, I always use and deploy the McAfee endpoint protection suite, including its firewall. The reason behind it is that we provide “Managed Security Services”, using the McAfee console web console we have centralized management that allows us to see the status of all security components including the antivirus, antimalware, web filter, and local firewall. Also, if you want to use all components from the security suite you buy as they are designed to work together to offer a better solution. I know it may sound biased when talking about McAfee solutions but after testing multiple security products in the market we can say that McAfee is the leader in the security realm.

  • Update your software

This applies to Operating system, Applications, and Security software. Microsoft releases security updates on the second Tuesday of every month. Open Windows Update to confirm that you have automatic updating turned on and that you've downloaded and installed all the latest critical and security updates. You can configure many applications to update automatically as well, if you don’t see the option to do so then you have to visit the application’s website and search for updates.

Many viruses are exploiting applications vulnerabilities so even if your Operating System and Security Software are up to date malicious software can find an open door through an application. Here at JDTech, we always recommend to test the update before deploying them to multiple computers. It is very common for updates to cause issues with system and other applications.

  • Adjust Internet Browser security settings

You can adjust the security settings in your Internet Browser to specify how much—or how little—information you want to accept from a website. Whether you use Internet Explorer, Chrome, Safari, or Firefox, you can edit security settings that will restrict or allow certain functions when browsing the web.

Microsoft recommends that you set the security settings for the Internet zone to Medium or higher. (If you use Windows 8, Windows 7, Windows Vista, or Windows XP Service Pack 2 and you use Internet Explorer to browse the web, your browser security settings for the Internet zone are set to Medium by default.)

Internet Explorer also includes a number of features, such as SmartScreen Filter, to help protect against viruses, spyware, and many other kinds of malicious, deceptive, or unwanted software. Google Chrome has a setting to “Enable phishing and malware protection” that scan sites for malicious content, and Firefox has security settings that tells you if you try to access a website that known to be use for malicious purposes. The point is that All browsers have built it security settings, make sure you take advantage of them and adjust them as you see fit.

  • Download and install antivirus software

There are many antivirus solutions in the market today, from complete endpoint security suites to just antimalware. In our case, we deploy McAfee security solutions. We are a McAfee partner and deploy McAfee SaaS endpoint solutions, though we also work with all vendors and adjust to the preferences and policies of each company, our experience is that McAfee is the leader in the security realm which solutions can be complemented to create a solid, robust security infrastructure.

Microsoft Security Essentials helps protects your computer from viruses, spyware, and other unwanted software. Avast, AVG, Avira, Panda are example of free solution available right now, though you may not pay upfront you’ll most likely end up paying down the road when implementing a real solution. Not to say that they are all bad in and of themselves, I know they can be used to at times for basic protection and removal but they will never offer a full blown endpoint security service.

We have deployed fortune 100 endpoint security protection for small businesses in New York and New Jersey at a small businesses budget. As an example, we have implement complete endpoint security solutions for small businesses including the software licensing and proactive monitoring and support for as low as $45 a month. Imagine having all your office devices protected and monitored using the most advance cyber security solution for such a price. Contact us for more details about our security solutions.

  • Surf and download more safely

The best defense against spyware and other unwanted software is not to download it in the first place. Here are a few tips that can help you avoid downloading software that you don't want:

  • Download programs only from websites you trust. If you're not sure whether to trust a program you are considering downloading, enter the name of the program into your favorite search engine to see if anyone else has reported that it contains spyware. Files that end in the extensions .exe or .scr commonly hide malware. However, even files with familiar extensions such as .docx, .xlsx, and .pdf can be dangerous.

  • Read all security warnings, license agreements, and privacy statements associated with any software you download. Before you install something, consider the risks and benefits of installing it, and be aware of the fine print. For example, make sure that the license agreement does not conceal a warning that you are about to install software with unwanted behavior.

  • Never click "Agree" or "OK" to close a window. Instead, click the red "x" in the corner of the window or press Alt + F4 on your keyboard to close a window.

  • Be wary of popular "free" music and movie file-sharing programs, and be sure you understand all of the software that is packaged with those programs.

  • Use a standard user account instead of an administrator account.

  • Don't click links on suspicious websites or in email messages. Instead, type the website address directly into your browser, or use bookmarks.

  • Don't automatically trust that instant messages, email messages, or messages on social networking websites are from the person they appear to be from. Even if they are from someone you know, contact the person before you click the link to ensure that they intended to send it.

  • Use Internet SmartScreen Filter

SmartScreen is a technology that scans sites to tell if they are safe to access. It’s not to be confused with the web content filter since it doesn’t categorize the content of the site but rather it analyzes the code of the site to determine if it has malicious software that will be executed when visiting the link. It also determines if it’s a legitimate site by doing DNS lookups and checking the URL against a black list. Our McAfee endpoint security solutions offer SmartScreen filter solutions integrated as part of our other services, Internet Explorer and other browsers also have a similar built in feature.
