5 Free Antivirus Applications for Windows

Windows 7 is undoubtedly the best operating system Microsoft has ever released. and Millions of Windows 7 OS copies are sold so far and it’s setting many records. Being most popular OS also results in being most attacked operating system by various Virus, Trojans and other malware programs. Due to increased viruses and other malware programs, antivirus software are no more good to have apps, they are not must to have apps.

I was using Kaspersky paid antivirus on all my personal computers till I upgraded to Windows 7. When I upgraded to Windows 7, I had an option of either upgrade Kaspersky for Windows 7 or trying to out free antivirus apps. Instead of investing money on paid antivirus , I thought of evaluating free antivirus applications available in the market. For the past one year I’m using the free antivirus applications on 3 of my personal computers . In this one year time, I tried and evaluated many free antivirus software and in this post I would like to tell you about them.

1. Microsoft Security Essentials

Microsoft_Security_Essentials_free_antivirus_for_windows_7For a very long time Microsoft was depending on third party antivirus vendors to protect Windows PCs. It has proven very costly, due to increased virus attacks on Windows PCs. In order to protect its users , Microsoft dipped it’s hands in developing antivirus software and released Microsoft Security Essentials. Microsoft Security Essentials(MSE) is an absolutely free application that runs on almost all the version of Windows OS available in the market.

Let me confess you that I’m a big fan of MSE and all my three personal computers are protected using this antivirus. MSE is the most recommended free antivirus software by tech pundits and security experts. LifeHacker says

The release of Microsoft Security Essentials has changed the landscape of antivirus software. We’ve finally got a completely free application that protects against viruses, spyware, and other malware—without killing system performance like some of the "suites" tend to do. In my personal experience, it barely slows down the machine and rarely affects my work—and during a deliberate attempt to download some viruses (for testing purposes), it immediately found and blocked them from doing anything.

The best part of Microsoft Security Essentials apart from protecting against viruses is it’s efficiency in using the using system resources. It never slows down the operating system and disturbs your regular work. Thanks to Microsoft for developing it’s own antivirus and providing it for free of cost.

We strongly recommend Microsoft Security Essentials as the best free antivirus software available in the market. Get it and secure your Windows PCs.

2. Avast Free Antivirus

avast_free_antivirus_for_windows_7What makes Avast antivirus different from it’s peers is its ability to scan the system during booting process – something you don’t find in a lot of free products — or paid ones for that matter.

Avast is a good free antivirus that provides the same steadfast protection of well-known, pricier antivirus programs. But when compared to other antivirus applications, Avast is a bit slow in scanning the files as well as it tends to slow down certain day to day operations of you PC.

3. AVG Free Antivirus

avg_free_antivirus_for_windows_7AVG is the most widely known free antivirus available in the market for a long time. Before release of Microsoft Security Essentials, AVG was the favourite free antivirus. It has gone through some ups and downs over the years.

It has a fairly good record on detecting viruses but at times you may be annoyed with too many false positives. AVG Free antivirus is a stripped down edition of it’s highly expensive AVG Antivirus.

One of the most distinguishing thing about AVG antivirus is it’s compatibility with Windows 2000 operating system along with support to Windows XP, Vista and 7. Not many free antivirus applications  are compatible with server OS like Windows 2000.

4. Avira Free Antivirus

avira_free_antivirus_for_windows_7Avira is an excellent free antivirus application that protect not only Windows users but also Linux and Solaris users. It is very good at detecting viruses and scan speeds & resource utilization are among the best of free antivirus programs.

The only complaint users have about this application is it’s nagging nature of asking you to upgrade to paid version. May be once in a day you should have the patience to terminate the popup window.

5. Panda Cloud Antivirus

panda_cloud_antivirus_free_antivirus_for_windows_7Panda Cloud Antivirus is an unique free antivirus – it’s the first ever main stream antivirus to make use of cloud computing for detecting and eliminating viruses and malwares from computers.

To keep the virus detection definitions up to date, traditional anti-virus applications download the definitions updates at regular intervals. Cloud based antivirus uses their cloud system to identify new viruses and other treats. Relying on the cloud and a community driven database of virus information makes Panda a super cool antivirus solution. When it comes to resource utilization it uses  just 15 MB of ram while scanning the files. This makes Panda a best antivirus solutions for Netbooks and low resource computers.


When it comes to Windows PCs, we no more required to spend money on paid anti-virus software. We have a wide array of free antivirus software to choose and secure the computers. With my personal experience, I recommend Microsoft Security Essentials if you have genuine Windows OS copy. If you don’t have a genuine Windows OS copy, then consider Avira.

Do you agree with my choices? How are your computers secured from viruses?
