Antivirus software protects your computer from malware infections. This includes viruses, Trojans, spyware, rootkits and adware as well as worms. It can also assist in detecting and repair the damage caused by these threats.
Antivirus software is an essential tool to protect any computer and mobile device. They can help prevent attacks by hackers, as well as detect and remove phishing attacks, ransomware, spam email, and other malware. They can also scan and secure connected appliances such as printers and SmartTVs.
When selecting an antivirus program be sure to choose one with an established track record of passing numerous tests and receiving good reviews from independent laboratories. Organizations such as Virus Bulletin, TechRadar, NSS Labs and AV-Comparatives run tests and provide comprehensive analysis of various antivirus choices. They will tell you what security features they provide and how well the software does its job, and whether it’s worth the investment.
Traditional antivirus software relies on the signature or the binary pattern of a virus to identify it. However hackers have kept up with this, by creating polymorphic and oligomorphic viruses that encrypt their own parts or alter their appearance in order to not match the signatures of viruses stored in antivirus databases. Sandbox analysis is utilized by newer antivirus software to combat these sophisticated malware threats. The program executes the file within a virtual environment in order to determine how it behaves.
