Antivirus software safeguards your computer from malware-related infections. This includes viruses and Trojans as well as spyware, adware rootkits and worms. It is also able to detect and repair any damage caused by these threats.

Antivirus software is essential for any laptop or device. They can protect against hacker attacks, detect and eliminate phishing attacks, ransomware, and spam emails. They can also detect and protect connected devices like printers, SmartTVs, cameras and other devices from malware-related infections too.

When you are choosing an antivirus program make sure you choose one that has a long history of passing multiple tests and receiving favorable reviews from independent laboratories. Organisations like Virus Bulletin, TechRadar, NSS Labs and AV-Comparatives conduct tests and provide thorough reviews of different antivirus software options. They will tell you what protections are included, how well they perform and if the software is worth the price.

Traditional antivirus software relies on the signature or binary pattern of a virus to determine if it is. However hackers have kept up with this by releasing polymorphic and oligomorphic viruses that encrypt their own parts or alter their appearance in order to not match virus signatures stored in databases of antivirus. Sandbox analysis is utilized by modern antivirus software to combat these sophisticated malware threats. The program runs the file inside an environment that is virtual to determine how it behaves.
