Avast Ultimate is a security software with a high detection ratio and a host of other features. Its malware scan scored 100 percent in my tests. Additionally, its web security blocked phishing websites that were able to bypass Chrome's and Firefox's default security. Other features include a Rescue Disk, a secure browser for online shopping and banking, advanced tracker blockers and a VPN.

The user interface of the suite is simple. The main screen shows icons that clearly explain the functions of each tool. The color scheme for Avast is orange, white, and blue. It's easy to read and pleasing to the eyes.

In the Explore menu, you'll access more in-depth control options for each tool including custom scans, boot-time scanning as well as an automatic updater. You can also save specific kinds of scans in the "Scan Center", so you can run them again in the future.

One of the most advanced features, Avast's antivirus can help prevent ransomware attacks by monitoring your system for suspicious activity, and then encrypting any files that could be targeted. It can even detect a trojan horse (a malicious program that sneaks into your computer disguised as legitimate software) and stop it from running on your system.
