Cybercriminals are constantly tweaking their methods, so you need a complete antivirus program to guard against the latest threats. A good antivirus program can search, detect and remove viruses, worms, trojan horses and spyware. Certain antivirus programs offer additional security features, such as virtual personal networks with password management and parental controls, as well as phishing protection.
The antivirus software must also safeguard you from rootkits and keyloggers that can secretly record every single word you type into your keyboard including passwords and credit cards numbers. Also, it should be able to block ransomware that can infiltrate your computer and take files for ransom until you pay a ransom.
The most reliable antivirus software has a high detection rate of known malware, and it consistently scores well in independent testing laboratories. A well-designed security suite has other safety features like the detection system based upon algorithms that look for the kinds of behavior that viruses are known to exhibit. It should also have a firewall and some programs have a sandboxing option that allows you to run suspicious software within a controlled environment in which they aren’t able to do harm.
A good antivirus program updates often, typically once or twice per day. It should also be compatible with a variety of devices, ranging from PCs and Macs to smartphones and smart homes. Certain antivirus programs offer cheap introductory prices. Some offer monthly or annual subscriptions in addition to charging per device. The price of a program should reflect the amount of devices and types it safeguards, the frequency of updates, its ease of use, and other safety features.
