Best Free Antivirus Software

The Top Ten
1 Avast Free Antivirus

Avast free anti-virus is easy to use, reliable, secure's the protection of your computer, and its FREE!

I use avast. From my experience I know its really fast and reliable... Very good anti-virus. And its very easy to use

Very good. I just don't like the popups from it that I get sometimes, but otherwise it's really good.

Not a good antivirus. Installed and now I can't open the volume button, open Word and uninstalling Avast. thanks AVAST!

I have been using the same free panda antivirus for the last three years don't ask me how but I must confess it's the antivirus I trust the most.. It caught a "Recycler virus" when no other antivirus could.

5 BitDefender Free Edition

This is one of bad antivirus because its storage is too high and takes more time to install

6 Microsoft Windows Defender

Windows 8, 10, 8.1 and 7 operating systems official Anti virus it.

7 Avira Free

Avira don't request a lot of your structure as avast do and both is poorly protect you pc as all free security softwares do.

Avira is the best security for your computer other than military security

The only bad thing about Avira is that it's slow, other than that it's a great antivirus

8 Smadav

It's an portable antivirus. It's not powerful, but so easy to use.

10 Comodo Firewall Antivirus

It's the best, and I am an expert and have tried a lot. Comodo has shown me upon the years that it can not only protect, but also lets take control over the options and your PC, not like other security software which think that they know the best for you.

It's pretty best free antivirus acts fast on virus threats and viruses.
