Free anti virus software besides AVG/Avast?

I use AVG (which is the same as Avast) on my desktop PC but, it's interfering with one of my favorite Bible software programs. Delays it opening because AVG has tagged it as suspicious. It gives me the option to define PC Study Bible as safe which, I've repeatedly done. AVG is still messing the Bible starting up regardless. I run Win 11. Is there another free anti virus besides the above? Thanks.
