How to Choose the Best Antivirus Software
Antivirus keeps your devices safe by detecting, blocking and removing malware threats. It also scans for threats on your networks and protects against ransomware attacks that demand payment to regain access to encrypted data. It can also prevent malicious users from accessing sensitive systems by monitoring their behavior and accounts.
Traditional antivirus software relies on a database of known threats that is updated regularly (a good reason to set it to update automatically). More advanced antivirus solutions use cloud-based detection, which sends information about suspicious files to the cloud for analysis and enables the program to make more informed decisions about potential infections.
Many of the best antivirus programs offer a blend of these technologies. For example, some combine signature detection with machine learning algorithms and artificial intelligence to spot new threats based on their sketchy characteristics, while others use sandboxing, which runs a file in an isolated environment separate from the system, to see if it exhibits suspicious behavior.
The most sophisticated cyberattacks can evade conventional antivirus protection, however. For instance, APTs often start with an unobtrusive Trojan that doesn’t immediately begin downloading and executing code until it has infiltrated the network. Until then, the intruder may simply be running a legitimate service, such as a backup server, to collect internal data.
You should select an antivirus solution that scores high in security rankings and has a solid track record in detecting new infections. You’ll also want to choose one that doesn’t tax your device’s resources or slow down performance during active scanning. Lastly, you may be looking for additional features beyond basic virus protection, such as identity theft and social media monitoring tools.
