Avira Free Antivirus is a piece of software designed to protect a Windows system from viruses, ransomware, and malware. The app has a relatively small footprint, it takes little effort to install, and it won't slow your PC down. Any number of threats to your system can be thwarted with the help of this software.

Most security applications in the same family as Avira Free Antivirus are exceptionally large and cumbersome, but this software is quite a bit more efficient and compact. These features are due to the methodology used by the software to search for threats. Using a proprietary 'Protection Cloud' that analyzes local files in conjunction with a small piece of software installed on your system, the system can accurately and quickly assess threats. Older versions of this sort of software had to perform all the functionality on the home machine of the user, but the Cloud allows a good portion of that processing to be done outside your system.

Like most software in this category, you can use Avira Free Antivirus to perform a scan of your PC. Integrated browser safety functions offer protection in real time, and the software comes with free integrated VPN service. VPN stands for Virtual Private Network, which is essentially a method for privately browsing the web. With Avira Free Antivirus, users are able to use the integrated VPN functionality for up to 500MB. With this feature, you'll be able to anonymously browse the internet. You might even be able to use this function to visit sites that have been blocked by your ISP or your home nation.

Anyone with any level of experience operating antivirus software will find the UI of Avira Free Antivirus to be straightforward and comprehensive. The UI doesn't try to confuse the user with excessive options, so it's ideal for those who have limited experience dealing with this sort of software.

There are two primary scan varieties the software can perform. The 'Quick Scan' provides a summary of the most vital areas that need protection, and the 'Deep Scan' scrubs your entire system for any signs of a threat. Below the options to perform these scans are several options for improving your internet browser settings. You'll also see a number of protocols you can enact to add more safety to your online activities.

One option you'll see in the UI is the choice to take advantage of supposed 'Speed Up' functions. These functions will work to make your system as fast as possible by limiting active background processes to optimize performance. They will also search your system for any junk files that are cluttering up your system and slowing it down in the process.

Once you've got the software properly installed, it keeps itself optimized automatically. You can obviously adjust any settings you want at any time, and you'll be able to install all the additional tools you want through the UI. These might include the VPN service or the proprietary Scout Browser from the developers of the software.
