Is my current antivirus program enough to keep my computer running quickly and smoothly?

No, your current antivirus software is not enough to keep your computer running quickly and smoothly. A comprehensive security solution such as a malware and virus scanner, firewall, browser protection, and anti-phishing/anti-fraud protection is recommended for optimal security. Additionally, regular maintenance such as removing unused programs and files, updating drivers, and running disk defragmentations can help make sure your system is running at its peak performance.
