An antivirus is a tool aimed very specifically at detecting attempts to exploit vulnerabilities in the operating system or applications.

However, Microsoft provides inbuilt malware protection called Windows defender, which works well in detecting and removing different kinds of viruses and malware. Still, malware is getting smarter and becoming undetectable by Windows defender. To combat this, we need dedicated antivirus software to protect our computers from all such kinds of threats.

A good antivirus program should definitely have the ability to root out existing malware, but also, its task is to prevent any nasty programs from getting in. The best part is when we get these services free of cost.

How to Select The Best Free Antivirus To Download?

So what do we look for when selecting suitable antivirus for your PC? Antivirus software should do its primary job, which is detecting malware and able to delete them. Apart from that, here are some features to look for.

Useful Features to look for:

1. To start with, every antivirus product scans files on access to ensure malware can’t launch and also scans the entire system on demand or on a schedule you set.

2. Blocking all access to malware-hosting URLs is a nice way to avoid trouble. Many products extend that protection to also steer users away from fraudulent websites and phishing sites that try to steal login credentials. A few rate links in search results, flagging any dangerous ones.

3. Behavior-based detection, a feature of some antivirus products, is a two-edged sword. On the one hand, it can detect malware that’s never been seen before. On the other hand, if it’s not done right, it can baffle the user with messages about perfectly legitimate programs.

4. Other useful bonus features include preventing USB-based malware attacks, scanning for router weaknesses, and cleaning up traces of browsing history.

5. It should have the latest antivirus engine with constant updates for new malware. This will ensure that you are protected from the latest threats.

It is easy to install, and a straightforward interface makes it easy to use. Whenever you install it for the first time, it does perform a quick scan that should identify any potential threats to your PC.

Avira is another leading antivirus company that offers complete protection from viruses, malware, trojan, worms, spyware, and rootkits.

The user interface of Avira is not as simple and clean as Avast or AVG, it has a bunch of control and setting options that give you more control over the antivirus, but you may not get familiar quickly.

However, it does take less time to complete the scanning compared to other free antiviruses, and if you have less than 2 Gigs of RAM, you might notice a little performance drop during the scan process.

3. Malwarebytes

There are hundreds of new threats being spread every day. Sometimes these threats skip through your leading antivirus and get into your PC.

To deal with such threats, here comes Malwarebytes’ antimalware, which is technically not antivirus software itself. It is a second opinion to antivirus programs; Malwarebytes Anti-Malware Free is an excellent complement to any antivirus program.

The software has a laser-like focus on eliminating tricky zero-day malware from your PC.

The Chameleon feature, which disguises the software so malicious programs can’t find it, is worth mentioning. We recommend Malwarebytes Anti-Malware Free for every PC user.

Like Avast, Panda scored top marks for virus protection in AV-Test’s report.

Its interface is pretty but not as user-friendly as that of Avast. It also has a nice feature called USB Vaccine – this prevents virus attacks that occur when you plug in an infected USB drive.
