Avast is a well-known antivirus program for PCs. It provides protection against ransomware and other malware including bots, spyware, and Trojans. It also offers various useful tools, including a password manager, and VPN. This program also comes with the feature known as Device Lock that will help you locate your lost devices while keeping your data secure from unauthorised access. It uses a behavioral analyzer to identify new threats and can run a system scan with just a single click.

However the program’s malware protection isn’t perfect and it takes a long time to complete the system scans. This makes it not ideal for busy users. Its heuristic analysis is not as advanced as premium software and can result in false positives. Sandbox technology isn’t as effective as other competitors, either, but it does work effectively enough to keep the majority of malware from your computer.

Despite these limitations, it offers solid protection against Wi-Fi, files and ransomware. You can customize your settings and add exceptions to the scanning rules, and the application’s Scan Central and Online Security web extensions make it easy to locate and manage all of your security features.

Upgrade to Avast’s paid plan and you’ll get lots of additional features. These include the heuristic scanning feature that runs your files in an isolated environment to identify more sophisticated malware and a privacy advisor that can help you modify your account settings for Facebook, Reddit and Twitter to protect your privacy. You’ll also get a computer speedup, a secure web browser, and a password manager.
