When choosing an antivirus program for your PC, be aware of how it detects threats and viruses. The most effective antivirus software employs the heuristic method of detection, which is able to look for patterns that are typical of malware, even when they haven’t been observed previously. They also examine your system and use Sandboxing, which puts suspicious applications in a controlled environment where they cannot do any harm. These methods are more reliable than relying on viruses databases alone.

Many antivirus suites come with other security tools, including password managers, VPN services and secure email. These are great if you require a tool that does it all. Be aware that they could also consume more system resources.
