Avast Antivirus is a consumer-focused security application designed to detect and block malware, unsafe downloads, and dubious websites on personal computers. It employs local scanning and cloud-assisted analysis to assess files and URLs for known or suspicious patterns. The software operates background services that continuously monitor files and web traffic for harmful content on both Windows and Mac systems. Avast offers a free version for personal use, with optional paid upgrades, and provides English-language downloads and support specifically for US users. It is developed by Avast, part of Gen Digital, which is publicly traded on Nasdaq under the ticker GEN. Independent testing organizations like AV-Test and AV-Comparatives evaluate Avast Antivirus, positioning it among mainstream antivirus solutions.
