Avast scan super slow

Is my Avast broken? I’ve noticed that since 2 months ago, it’s become slower when scanning flash drives or anything at all. I’ve read that disabling other security software in your PC might help that problem. So, I disabled my Malwarebytes but that changed nothing. Can someone help me with this? It’s very annoying and frustrating.
