Top 3 Best Free Antiviruses

Being in the cyber security field I get few questions asked a lot , One of these questions is “What is the best antivirus ?” and the question that follows after that is “Is it expensive?” or “Can you recommend some free Antivirus ?”. Every computer user comes to his question sooner or later, Depending on how much you know about computers and antivirus is the key between getting scammed or staying protected.

In India novice users are scammed in to using non-trusted or in-efficient antiviruses all the time , the biggest scammers are the retailer from which you buy the Computer / Laptop etc. They will push you in to buying these antiviruses, which do not provide the sufficient amount security that is needed all the while making you pay a large sum for it. Many of the retailers also sell pirated Antiviruses and get away with it. Any problem later caused by viruses will always be the customers fault and the best solution will always be formatting the system.

In this article I will be giving my personal experience as well as recommendations of these three “Best Free Antivirus” you can have, while providing the necessary security that your system needs. All of these antiviruses are best in the class and my numbering dose no mean their Performance level but it is their to assign them numbering while progressing ahead.

3. Bitdefender Antivirus Free Edition

Ratings :

PC Magazine Rating : EDITOR RATING: EXCELLENT (4.5)

CNET Rating : 4/5 Stars

Summary :

Bitdefender is a Romanian Internet security software company, represented through subsidiaries and partners in over 100 countries. Installing Bitdefender Free is quick and easy. During the process, it downloads the latest version and scans for active malware. You need to sign up for a Bitdefender account to activate it (or sign in if you already have one). The premium edition’s main window isn’t especially busy, but the free edition is simplicity itself. There’s a button to run the full system scan, a drag/drop spot to scan specific files or folders, and a timeline of recent activity. That’s it. There isn’t even a separate scan window. When you launch a scan, the scans progress appears in the events timeline.

Bitdefender is a genuinely good antivirus and is preferred in a business environment because of its reputation within Infosec community. Bitdefender free version dose no provide other complimentary tools within the UI, Such as Deleting Temp files, registry backup etc. Which is an issue if you are looking for an antivirus which dose multitasking within the same interface. I personally prefer any tool which can be versatile so that I can use multiple functionality within the same interface. Which reduces stress on the system of having too many tools on board.

System Requirements –

Operating system: Windows 7 Service Pack 1, Windows 8, Windows 8.1, Windows 10

Hard disk space: 2 GB available free hard disk space (at least 800 MB on the system drive)

Memory (RAM): 1.5 GB

2. Avira Antivirus Free Edition


Ratings :

PC Magazine Rating : EDITOR RATING: GOOD (3.5)

CNET Rating : 4/5 Stars

Summary :

Avira Operations GmbH & Co. KG is a German multinational security software company that provides antivirus software, Internet Security, Privacy, Identity and Performance tools for computers, smartphones, servers and networks, delivered as both software and cloud-based services.

Avira Free Antivirus protects PCs using traditional signature-based malware scanning, augmented by behavioral monitoring for subtler signs of an infection. Both constantly operate in the background as well as during active scans. Avira’s Cloud Protection examines suspect items uploaded by the 100 million users of Avira software, and quickly pushes out definition updates. Cloud Protection collects malware samples from you by default, but you can opt out.

Avira dose provide multiple tools along with its free anivirus , Quarantine is my personal favourite feature it keeps the deleted malicious files separately in a vitalized environment in which they cannot harm the system and the user has the ability to take the file out of quarantine.

CNET Rating : 4.5/5 Stars

Summery :

360 Total Security is a program developed by Qihoo 360, an IT company based in China. 360 Safeguard’s focus is on stopping computer viruses, malware, and trojan horses, and providing security patches for Microsoft Windows. 360 Safeguard trojan horses scanner is cloud-based. A heuristics engine is built into the scanner. 360 Total Security users are able to upgrade to premium membership to enjoy an ad-free experience, the stylish Lively Theme, and more exclusive discount.

I personally recommend this antivirus only because it has the best Security and functionality to be the best in its class.

  1. It uses both Bitdefender and Avira antivirus engines on the background as well as providing Qihoo’s own antivirus engine so you get THREE antivirus engine all comprised within one antivirus.

  2. The functionality provided by the antivirus is huge compared to other two antiviruses.

  3. The tools provided alongside the antivirus is the best thing of all.

The best thing about this antivirus is that there is no difference between premium and free version , the premium version is only ad-free and provides various themes but the ads are placed so subtle that we hardly notice it while using the antivirus.
