Avast Free Antivirus closes the gap between free minimum and paid-for software offering the protection that is just as satisfactory as many premium apps offer. You can install Avast in several ways: with the easy-installation route or in customizable mode, that lets you pick those components you need the most. On that note, you also do not need to register with Avast Free Antivirus to take the full advantage from it.
Another point in Avast’s favor is its barely noticeable system impact. However, it takes longer to complete the antivirus scan, Avast was never noticed to slow down file copies, application launches or web browsing.
Avast is a proven highly efficient defense against a diverse range of threats from pop-ups and PUPs (potentially unwanted programs) to vicious ransomware. Avast will recommend you to run a boot-time scan to clean up your system thoroughly. This procedure minimizes interference from the malware before your operating system has booted up completely.
Avast Free Antivirus goes beyond the expectations of a free antivirus program by including a password manager and a home-network scan.

Powerful Password Manager
Avast master manages all your web passwords helping you to create a strong one with colored indicator ranging from green to red. Avast password manager also has web integration which can save all your login credentials to fill them in every time when you revisit the website.

Protected from all angles
An out-of-date software can become a rabbit hole leading noxious malware to your computer. Avast Free Antivirus bolts this door with the Software Updater scanning your computer to report afterward about outdated software it finds.
Secure browsing is another handy feature of avast. It integrates with your browser allowing you to benefit fully from Avast. First, it marks safe or unsafe web sources right in the search results. Next, it can scan the website you are visiting for different types of tracking agents.
Avast Free Antivirus also offers online technical support and its technicians promise to respond in 24 hours of a query.
