If you’re looking for a simple and easy-to-use free antivirus tool, you should download Avast Free Antivirus. As the name suggests, the program is free to use and comes with a range of features that help detect and delete viruses, spyware, ransomware, and malware. It also keeps a constant check on the apps installed on your PC to highlight any new or malicious behaviour.
Additionally, the program can also scan your network to detect any threats and identify vulnerable points. The latter could be anything from weak passwords to default settings. Once threats are detected and removed, Avast prevents them from infecting your PC again. The software also searches for threats on your email, files, P2P transfers, and instant texts, to ensure your overall security.
