Avast Free Antivirus is an antivirus that needs no introduction. Praised by many users for its PC protection, Avast (no longer avast!) is a multi-function security program that's very easy to use and one whose power is no longer in doubt. Everything you need to secure your PC

for your computer. It continually updates its database of virus definitions to guarantee maximum protection against online threats, including viruses, spyware and rootkits. Five types of scans are available to verify their presence on your PC and eliminate them.
Other types of scans are available, not just for viruses, but to optimize and improve the performance
of your PC. First off is a feature that allows you to scan your computer to see if any programs need to be updated. Then, the newly added features help detect any deficiencies in terms of performance (the Cleanup module), and scan your local network to detect security flaws affecting your Wi-Fi, your connected devices, or your router.
To make things easier when performing these scans, the 2016 version of Avast Free Antivirus includes the Smart Scan feature, which combines all the essential scans into one single unified scan.
