Avast is among the most intuitive anti-viruses, with all features accessible through one menu. It is also simple to understand, with concise explanations placed next to each feature, so that you will not be confused about what it does and how it works.

The pre-installed PC Optimizer makes your device run more efficiently by snoozing unnecessary background processes, freeing memory, erasing unwanted applications and files and boosting battery life, allowing you to play games with a longer duration. Upgrading to a premium plan provides you with a lot more performance-enhancing tools including security against phishing attacks, a sophisticated firewall, and webcam protection.

Avast provides two ransomware security modes: smart and rigid. In smart mode, only a few lists of trusted apps can be allowed to alter your files. If an app that isn’t on this list attempts to alter your secured data, you are instantly notified and asked for authorization. In strict mode, all modifications are blocked unless they are approved by you.

It also has other useful functions, such as the ability to review the quarantined files of NTFS disks and to turn off notifications regarding the newly developed „block“ rule (enabled default). Overall, Avast is the best antivirus that is lightweight and will perform well in 2023. It could be a significant influence on system performance when too many features are enabled. This is easily avoided by deactivating unneeded tools or doing a full Avast cleaning every now and then time.
