10 Best Free Antivirus Software

An antivirus is computer security software that protects the computer from all types of malware by constantly monitoring the execution of programs and files and stopping or removing any malicious program using its various technologies. It also monitors Internet surfing to scan network traffic and protect the computer from harmful websites, and phishing attempts.

Any type of data coming from the Internet or on removable storage devices such as compact disks or USB flash drives is scanned to prevent any kind of malware attack on the computer. An antivirus is the first software that should be downloaded and installed on a Windows PC. Here, we take a detailed look at the 10 best free antivirus software available for computers today.

1. Avast Antivirus

Avast Free Antivirus protects against viruses and other malware using its renowned antivirus engine and other technologies. This program has various security-related tools, and there are settings for everything. You can customize this program to your liking. Avast is a crowd-pleaser, and consistently tops antivirus lists.

All types of scans are present here – Smart Scan, full virus scan, and an option called Other Scans that links to other advanced and customized scans. Four protection shields are included in the free version – File Shield, Behavior Shield, Web Shield, and Mail Shield.

Since the ownership of AVG, Avast’s detection ratio has gotten even better as they now have AVG’s signatures in their database as well. Avast Free includes a cloud scanning technology called Cyber ​​Catcher, which helps them keep their antivirus light on user system resources. Avast now includes AVG’s Behavior Shield inside their product, which means better malware detection. Remember the dedicated ransomware protection component is not available in the free version.

Additional security tools include rescue disk, password, and game mode. The sandbox feature is only available in their paid software.

There are various messages about their paid products at the bottom of the main window and on the sidebars of other windows. They constantly remind you to consider purchasing their premium products.

2. AVG Antivirus

Since Avast’s acquisition of AVG, the signatures from both companies have been merged. The merger of signatures has made AVG’s detection ratio even better. Along with all of its technologies, AVG now also includes Avast’s CyberCapture technology, which is a cloud malware scanner engine. The dedicated ransomware protection component is not available in the free version.

The downside of AVG antivirus software is that it constantly advertises expensive updates, with a permanent bar at the bottom of the window reminding you to upgrade to full protection, unlocking all the features of AVG Antivirus.

Bit defender Traffic Light has the following features – advanced malware filter, protection against phishing attacks, trackers identifier and link scanner. Bitdefender Photon is not available in the free version of their antivirus.

Overall, this is a great product but if you want to play with some settings then look elsewhere as you won’t find any here. Only two scan modes are available for free users. One is System Scan, which is a full computer scan. The other scan mode is like a custom scan. You can drag and drop selected files or folders into the program window to start scanning. A very capable program yet very lightweight with a minimalistic design and packed with award-winning technologies.

5. Panda Dome

Today’s Panda Dome has its roots in a product called Cloud Antivirus, first released by Panda Security way back in 2009. Panda was the first free cloud-based antivirus for Windows. That product’s unique selling point was a cloud scanning and analysis feature that made the product super light on the security software provider’s infrastructure and not heavy on the user’s system. In 2014, Panda relaunched Cloud Antivirus as Panda Free Antivirus with offline protection.

The features like Behavioral Blocker, Heuristic Analysis, Process Monitor and USB Vaccination combined with offline malware cache provide a strong protection from all types of malware while at the same time shining a light on the system. Three types of scans are supported – Critical areas, Full Scan and Custom Scan.

A bar reminds us that this is free protection, and that we need to upgrade to full (paid) protection. Panda displays news and promotions of its own products. Panda safely downloads and installs the Panda Safe Web program, even if you do not agree to it, and once installed it does not uninstall with the removal of the antivirus.

There’s a small non-intrusive banner image at the bottom of the program’s home screen, and the Upgrade to Pro tab has a comparison table between the free and Pro versions. Both of these serve as promotions for their Pro version.

In terms of features, the current Sophos Home doesn’t have much, with most of the features only available on the online dashboard. On the locally installed product, you get only two options – one starts a scan, and the other takes you to your online account dashboard aka the Sophos Home dashboard.

Sophos Home Free only supports full system scans, and doesn’t let you perform quick scans or setup custom scans. However, you scan your files and folders using the Sophos Scan option from the right-click context menu of files and folders. If only they had added all those options present in the online dashboard to the local product, life would have been much easier for users.

It is heavy on the system, a lot of processes running at the same time in the background. Regarding ads and PUPs, it is completely clean, there are no sponsored programs or services in the installer or antivirus.

9. Comodo (Comodo Antivirus)

Comodo Antivirus protects you using more antivirus technologies than any other free or paid antivirus product. If you use their Free Internet Security you add another layer to your protection, which is the firewall.

Comodo Antivirus uses the following technologies to protect your computer from malware.

• Antivirus signatures
• VirusScope behavior blocker
• Defense+ HIPS
• Sandbox virtualization
• File Rating Cloud protection
• Comodo Secure DNS
• Comodo Online Security web browser extension
• Firewall (available in Internet Security product)
• Web filtering (available in Firewall and Internet Security product)

Comodo has a complete set of scan options available – Quick Scan, Full Scan, Rating Scan and Custom Scan. There is an inbuilt tool to create a bootable Comodo Rescue Disk. Comodo is the only free antivirus that supports multiple themes; you have the option to choose from four different themes. Another good feature is password protection that locks and secures the settings and the program itself from wrongdoers.

Comodo Antivirus is the most polarizing antivirus product in the computer security industry. It is loved by enthusiasts for the multiple levels of protection that the program offers, the configuration options it supports, the HIPS feature called Defense+ that intercepts every action taken by files and programs, the virtualization feature called Sandbox that automatically runs a suspicious application in a virtualized environment, and cloud protection.

But, these advanced technologies also bring some downsides. HIPS makes the program very sandboxable, something that most users don’t like. Sandboxing can automatically run a legitimate program in a container, and there may be a problem of false positives. Anyway, these are secondary issues. The defense provided by Comodo is almost impenetrable.

Its installer includes some third-party services that make changes to the default configuration of your web browsers. Make sure you clear those checkboxes while installing Comodo.

If you are looking for the best free multi-layer protection for your computer then Comodo Free Antivirus might be the best free antivirus for you.

Available: Windows
