Kaspersky Security Cloud Free is probably the best free AV at the moment in terms of protection and resource usage.
If you wanted to still use Avira, but without all of its 'extras', you can use the AV-only installer - https://www.avira.com/en/start-download/product/1129/RnZHNUpuemRxeTdRV2hiZ2NGaENQTFQzNy8yRHRwb0UxekZIaktpOG1Rb2JSdG5IK01Xc0wrY0J2dz09
Other good options are Sophos and Bitdefender.
