Today more than ever, it is of the utmost importance that you have one or more security apps protecting your computer’s sensitive inner workings. The internet has become a dangerous place, with malware, ransomware, and identity theft waiting around dark corners. While default security measures like Windows Defender aren’t bad and have enhanced features like aggressive blocklists, there’s no harm in keeping your system secure with proven third-party utilities.
