Free Antivirus Software Download

With modern technologies advancing every day, some of these technologies are used to create panic, confusion, frustration, and sometimes loss of data through the use of cyberterrorism and virus production, manipulation, and distribution. Fortunately, many large companies, independent hackers, and advanced users within the IT community itself have come forward with a wide variety of antivirus and antimalware software to combat these intrusions into peaceful cyber living. In this article, we will evaluate and compare some of these programs so that you may return to a normal computer experience without the fear of being attacked by viruses and malware.


AVG is a very popular antivirus program and frequently updates their database so that you can always be one step ahead of the latest threats. AVG has a powerful system for detecting and destroying viruses and other forms of malware, however, it does have its drawbacks. AVG can significantly lag older computers as the program uses a lot of RAM when running a full scan. AVG also has a habit of labeling innocent files as virus-infected. This type of error is known as a false positive. Despite AVG’s downsides, it does provide a formidable defense. The latest versions of AVG have been upgraded to run faster, use less RAM, and have been outfitted with new detection methods that defend against “phishing” websites. AVG is also bootable in MS-DOS and can create a “rescue disk” that allows you to run the program when a virus has virtually taken over your computer.


Avira is a powerful, free antivirus program that works in Windows, Linux and other operating systems. Avira protects against spyware, malware, viruses, spam, and phishing websites while also serving as an efficient recovery program. Avira performs a deep scan of your entire hard drive while protecting your computer in real-time. Avira is well known for its annoyingly loud beeps that the program makes whenever it detects a virus. Avira also frequently makes false positives which can lead to some programs having missing files when you tell Avira to delete all viruses. Regardless, Avira is a very well known program and is highly recommended within the IT community.

Spybot Search & Destroy

Spybot Search & Destroy is also a well known antivirus program that is capable of performing deep scans of your computer. Spybot Search & Destroy is powerful yet seems to be rather outdated as it fails to detect some viruses that other antivirus programs find. Spybot Search & Destroy is a classic antivirus program within the IT community and features a quick scan, a deep scan, a real-time defense scanner, and a web-based protection service. Spybot Search & Destroy is a free program and is fully dependent on donations.


Ad-Aware is an extremely popular antivirus program and is probably the first thing that comes to mind when you think about antivirus protection. Ad-Aware offers a quick scan, deep scan, web-based protection, and a real-time guard that protects you from not only adware, but spyware, malware, and viruses as well. Ad-Aware is a free program and is extremely easy to use.

Windows Defender

Windows Defender is the only free antivirus program offered by Microsoft. While Windows Defender is better than not having any antivirus protection at all, the program has a few serious drawbacks. For one, the database for Windows Defender is outdated and does not detect as many threats as other antivirus programs. Also, Windows Defender does not give you as many controls as other antivirus programs, significantly lowering your protection.

Spyware Terminator

Spyware Terminator is by far the best antivirus software available. It provides a deep scan that quickly finds any threats on your computer and uses very little RAM to do so. Both the fast and deep scans include a progress meter that displays the percentage of the scan that has been completed. Spyware Terminator also includes a real-time shield to defend against viruses and malware. Spyware Terminator’s real-time shield is very sensitive and therefore regulates access to all programs that are trying to be opened, even if done so manually. You can set the shield to specifically allow certain types of programs but even without doing so, Spyware Terminator hardly gets in the way at all. The program also protects you while using the Internet and regulates downloads as well.
