Antivirus is software that protects your computer from malware (malicious software) threats like viruses, Trojan horses and worms. It uses real-time protection to scan and identify malicious code, then removes or quarantines them and blocks any attempts to infect more files or devices. Most antivirus programs also have features to prevent hacking and extortion by blocking pop-up ads and identifying suspicious websites or activities that might lead to your data being stolen or ransomed.

Traditional virus detection depends on signatures, which are the equivalent of digital thumbprints. Each time a new type of malware appears, its signature is added to the antivirus database and the program warns users about the threat. However, hackers are staying one step ahead by writing oligomorphic and polymorphic malware, which encrypt parts of themselves or otherwise modify their structure so they don’t match a virus signature in the antivirus database.

The best antivirus for 2019 detects malware with technology that goes beyond just scanning your computer for existing threats. It also looks for sketchy behavior that might signal a malicious intent, such as attempting to delete files, monitor keystrokes or change settings on other programs. Many modern antivirus programs use cloud analysis to bolster their ability to spot brand-new threats that haven’t yet been seen by the security community.

When choosing an antivirus, look for a product with a high detection rate in controlled tests. That doesn’t necessarily mean the program will catch every single piece of malware that is released, but it will significantly reduce your chances of infection.
