>> Microsoft Security Essentials
My favorite and recommended. Released by Microsoft in late 2009, Microsoft Security Essentials sports more than a typically verbose Microsoft name: it’s also a really good antivirus. Lightweight enough to run on older machines without crippling their performance, yet competent enough to handle most viruses and malware out there.
The best part of MSE is its simplicity. As you can see, the user interface is really clear, with large buttons for the most basic functions. Its goes well even if you’re a computer freak or a noob headed “i use a computer for facebook” kid. (DON’T MIND)
Avast! Free Antivirus is my new top pick for the best free antivirus software in light of recent developments. Avast has steadily been improving its detection rates over the past few years and now ranks with the some of the best.Avast has the most features of all the free antivirus with full real-time capabilities including web, e-mail, IM, P2P and network shields, boot-time scanning, and a behavioural blocker. The new version 6 brings even more features including an internet site ratings plugin, script malware protection and a limited (non-configurable) sandboxing feature. .Lastly Avast is also light on resources. But if you really like to download cracks and Hack Tools like me, then i prfer not using it, when AVAST! goes through crack files it destroys it.
Anti-Virus Free from AVG is the third best free antivirus software available. AVG Anti-Virus Free is a full-fledged antivirus and antispyware tool, includes an email scanner, link scanner, scheduled scanning options, automatic updates, and more. There is no need to pay for an antivirus program when the best free antivirus software in the world is just a download away.
The huge number of premium features, frequency of updating, and install-it-and-forget-it aspect of AVG’s Anti-Virus Free really do make it the best of the best free antivirus programs available today.
Avira AntiVir Personal Edition is another high quality free antivirus.AntiVir is still a top notch antivirus scanner with outstanding detection rates of malware, higher than almost every other antivirus according to tests. AntiVir is still a good choice for a free antivirus scanner, particularly for high risk users. If You’re asked to register during the Avira AntiVir Personal installation but it’s optional. Just uncheck the box and continue with the install.
>>Panda Cloud Antivirus:
Panda Cloud Antivirus protects you from several kinds of malware threats – viruses, worms, Trojans, adware, and more – just like all the other free antivirus programs in this list.
What makes Panda Cloud Antivirus one of the best free antivirus programs is that it does its job from “the 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.
So forget about computer viruses and Have Fun!!
