There are several kind of viruses for examples, trojan, spyware, ransomeware that can completely disrupt you professional life and as well as your personal life.

So, what is the best anti-virus for your computer? Let me tell you this very clearly there is no concrete ans to it. The definition of best anti-virus varies from different aspects to its users own priorities. There is a organization called AV Comparatives who conduct test between different anti-virus and rate them. So, in this blog I am going to list down top 5 free anti-virus based on their research combined with my own personal experiences.

Avast and AVG

I mentioned Avast and AVG in same group for a particular reason. These two are the most popular anti-virus program among the free anti-virus users in terms of download and installs. They used to be the competitors but in 2016 Avast acquired AVG for $ 1.3Billion. But still operates under different brand. So both are more or less same, very easy to install and use. Avast is little bit high in detection where as AVG is less power hungry. Now it’s up-to your own priority which one you like.


Panda is one of best free anti virus previously known as Panda Dome. According to the test conducted by AV Comparative on July, 2017 it ranked it the best anti-virus for Real World Protection. It also records perfect detection rate in multiple test with very minor positives. It has active anti-virus detection for any running program. It can also detect the spyware and adware running in the background. The USP of Panda is it works in Cloud meaning the hard antivirus work that typically slows down a computer is done on computers elsewhere on the Internet, freeing up your computer to work like it should and protecting you from malware even better. It has like gaming mode and many other features. I would definitely recommend you to give it a try.


Avira is among the most known Anti-virus program and maybe the only one that gives full free security suite which includes Essential antivirus protection, Tune-up utilities – starter kit, Password manager, Personal privacy assistant, Avira Home Guard, Browser tracking blocker, Secure search engine. It ever bundles with VPN also. So, if your are some one who is looking for total suit protection from cyber threats then Avira is definitely one for you. Avira Community is growning very fast and giving Avast a hard competition in the free anti-virus segment.

Bit Defender

If we go by the test conducted and result published by AV Comparatives then Bit Defender is one of the best anti-virus if not the best. According to my own experience it is the lightest anti-virus among this list and it’s detection rate is also very high. Bit Defender is easy to install and operate. It is minimalist in nature and does not hog all the power of your system unlike many other anti-virus programs. So, if you are someone who is using low-end machine or old system then Bit Defender is way to go.
