Antivirus software protects a device’s computer system from harmful files. These are also known as viruses including spyware, adware keyloggers, cryptojackers and rootkits among other types of malware. They can damage a computer system or be used to steal information and data. The most reliable antivirus programs have been proven to protect against these threats and others that are being developed every day.
The most sophisticated security systems come with multiple layers of security, including behavior-based detection. This looks at the behavior of an object to determine if it is behaving abnormally that could indicate malicious intent. It is useful with signature-matching and heuristics, as well as other traditional methods of detection.
It is crucial to find a program that regularly updates its virus definitions to stay ahead of new threats. Some programs require manual updating and others update automatically. It’s also worth determining the amount of resources it uses for scans and updates. You do not want a slow resource-hungry software that can cause your computer to run into problems.
Beware of emails that attempt to lure you into downloading an antivirus program that isn’t there. They’re usually scams, and they’re created to get you to believe that they are downloading an antivirus program that does not actually exist. Also, do not click on any download or links that are suspicious in these emails. Instead, research and confirm virus information via your anti-virus provider or other trusted sources.
