Cybercriminals are constantly changing their tactics, which is why you require a comprehensive antivirus to be protected against the newest threats. A good antivirus program can scan, detect and delete viruses and trojan horses, worms, and spyware. Some programs also offer additional security features, such as a virtual private network as well as parental controls, password management and phishing protection.

Antivirus software should also protect against keyloggers and rootkits that can record all the information you write on your keyboardincluding passwords, credit card numbers. It should also protect against ransomware, which could take over your PC and hold files hostage until you pay a ransom.

The best antivirus software has a high detection rate of malware that is known and is consistently rated very well in independent testing labs. A reputable security suite will also include other safety features, including a heuristic-based detection system that analyzes the types of behaviors that viruses are known to exhibit. It should also have security features like firewalls, and some software offer a sandboxing feature which allows you to run malicious programs within a controlled environment in which they are not able to cause harm.

A reliable antivirus program updates frequently, usually once or twice per day. It should also work with a variety of devices, ranging from PCs and Macs to smartphones and smart homes. Some antivirus programs offer low initial prices. Some antivirus programs charge monthly or annually, while others charge per device. The cost of a software should be based on the variety of devices and types it protects, the frequency of updates, its ease of use and other security features.
