I would use kaspersky 2020 security cloud free. There is no difference between KSCF and KAV, almost
for internet security, you get antibanner, firewall and application+TAM
but I would tweak it for maximum performance possible. Default setting is too heavy for my liking
- File antivirus: Scan on execution
- Disable encrypted connection scanning
- disable script injection
- disable unnecessary components such as IM antivirus or mail antivirus if you don't use
- check performance submenu: uncheck all types of scan (idle, rootkit,...) and check anything with the word "Postpone...", check gaming mode, release resources
- wait a few days for it to collect enough cache
trust me, they won't lower your protection
