Avast is one of the most popular antivirus programs for PCs. It offers protection against ransomware and various other malware, including spyware, bots, and Trojans. It also comes with various useful tools, such as a password manager, as well as VPN. This program includes an option to lock your device which assists in locating lost devices and shields your data from unauthorized access. It employs a behavioral heuristic analyzer to spot new threats and can run an entire system scan with only one click.

However the program’s malware protection isn’t perfect and it takes time to complete the system scans. This makes it not the best choice for busy users. Its heuristic analysis is not as sophisticated as top software and may result in false positives. Sandbox technology in the program isn’t as effective as other competitors, but it does perform well enough to keep the majority of malware out of your computer.

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

Upgrade to Avast’s paid-for plan and you’ll be able to take advantage of a variety of additional features. They include the heuristic scanning feature that runs your files in an isolated computer in order to detect more sophisticated malware as well as a privacy advisor that can help you adjust your account settings for Facebook, Reddit and Twitter to safeguard your privacy. Additionally, you get a password manager and a secure web browser, as well as PC speedup, which optimizes the performance of your PC.
