Antivirus software shields your PC from malware infections. This includes viruses, Trojans, spyware, adware, rootkits, and worms. It can also identify and repair any damage caused by these threats.
Antivirus software is a vital tool for protecting your device, including a mobile or computer. They can help prevent attacks from hackers, and detect and eliminate phishing attacks, ransomware and spam emails. They can also protect and scan connected appliances, such as printers and SmartTVs.
When choosing antivirus software select one that has been thoroughly tested and praised by independent labs. Organizations like Virus Bulletin, TechRadar, NSS Labs, and AV-Comparatives conduct tests and provide detailed analysis of various antivirus alternatives. They will tell you what protections are included in the program, how they perform and if the program is worth the investment.
While traditional antivirus software relies on the signature or binary pattern of a virus to determine it as a threat, hackers have stayed ahead of this by creating oligomorphic, polymorphic, and most recently metamorphic viruses which encrypt a portion of themselves or change their appearance to match the signatures of viruses in antivirus databases. Sandbox analysis is used by the latest antivirus software to combat these sophisticated malware threats. The antivirus software guide program executes the file in the virtual environment to observe how it behaves.
