If you’re looking for antivirus protection make sure you choose a software that can detect and deflect malware. Malware is a software created to harm laptops, computers, take data, or corrupt systems. Malware can be spread via malicious emails, USB drives with questionable content, or via online ads.
Security software can detect and ward off cyber threats. The top antivirus programs also offer excellent customer support. Some programs can be back by a money-back guarantee.
The majority of the antivirus programs we test for this report included many features to prevent or detect infections. The signature- and heuristic detection compares programs or files with known malware signatures. The heuristic tool also looks at the behavior of the program in search of anomalies and unusual behavior.
Many programs also offer a firewall, which monitors activity and blocks certain ports to stop attacks. Some include ransomware protection which encrypts your data so that you’ll need to pay a fee to decrypt it. Others offer web protection via browser extensions or plugins, that block sites that are suspicious or prevent you from accidentally giving your personal data to criminals.
Many of these programs rely on cloud-based verification of URLs, data files and other information. They upload an inventory of running and installed applications, the metadata of files, and their signatures to the cloud for a check against databases of the company. The companies differ in the way they share this information and whether you are able to opt-out.
