If you are not a software developer then maintaining a Windows PC without any virus attacks is a big headache, actually it’s impossible now a days. Only techies and professional software developers can handle big time tasks like that themselves. But in case of normal PC users like us, this problem can be easily solved if we install a famous antivirus software in our PC.

But popular Antivirus software such as Quick Heal, Kaspersky, McAfee, Norton etc..; are not available for free. They are very expensive because of the features and high end protection they provide.  So not everyone can afford them. This is why we should opt for best free antivirus software. There are many free antivirus software available online, but only few of them are best and offers high functionality as promised. We have shortlisted five of those best free antivirus software just to save your precious time.

Conclusion : 

All the above specified antivirus software works equally well. But in case of free antivirus only limited functionality is supported even though they serve well at their current level. However virus threats are increased in the recent times and if you use your PC for online purchases and business options, my choice for you is to choose one of the premium version. But in case of a normal Home user, the above mentioned best free antivirus are more than enough.
