Both K7 Ultimate and Webroot Security Plus are great choices. However, Webroot is known to be lighter on system resources, making it ideal for gaming laptops. Other lightweight options to consider are Bitdefender Antivirus Free Edition and Avast Free Antivirus.

Light, like for a 16GB-RAM system, I would go with the built-in Windows Defender, used along with MalwareBytes browser guard and free scanners from different vendors including ESET and Sophos.

For a better detection rate and free, I would go with Avast, or Kaspersky if "not afraid of the FSB."

For better detection rate and paid, I would go with Bitdefender or ESET.

K7 and Webroot are both very light, but K7 provides better protection and would be a better choice. ESET and Kaspersky, which have both been mentioned, are much better options. ESET is very light too and Kaspersky is pretty light these days too. Microsoft Defender is reasonably light, but the others often will have less system impact. However, since no doubt the PC has a fast CPU, Defender may not impact performance much.
