The most common use of antivirus software is to defend against different types of viruses, worms, Trojans, and other malicious software infections. Generally, these malicious programs are designed for a variety of purposes, including stealing personal information, launching distributed denial-of-service (DDoS) attacks, and disrupting the normal operation of a computer or network.
Antivirus software is also capable of detecting and removing spyware and adware. Spyware often comes packaged with legitimate software, and can track a person's activity online. It records executed keystrokes and can send that data to remote servers, allowing the criminals to gain access to passwords and other sensitive information. Adware, on the other hand, is designed to generate revenue for the developers by displaying numerous advertisement windows during everyday computer use.
Another benefit of antivirus software is it can improve the overall performance of a system. On top of preventing malicious software infections, antivirus software can detect and remove obsolete registry entries, program residues, and fragmented files from hard drives, all of which can have a negative effect on a computer system’s performance.
Virtually all security software packages now come bundled with a firewall and an anti-spam filter. While a firewall is designed to protect a network from unauthorized access, an anti-spam filter can help reduce the amount of junk e-mails in your inbox.
Finally, an antivirus software can also be used to detect and prevent phishing scams. Popular with online criminals, phishing scams aim to deceive people into divulging personal information, such as credit card numbers, passwords, and other sensitive data. Overall, an antivirus software is a powerful and reliable layer of protection for any modern computer system.
