I resolved the problem. I had changed msconfig to not load start up items. This caused Avast to start up and then quit. I changed the msconfig to load up everything then rebooted my laptop and now avast is running a bootscan as it should.

This problem has been resolved, thanks for your help.

Now I have one more question is it possible to still have a rootkit infection and not know it? I always run Malwarebytes and Avast as the two tools I count on all the time. Nut sure if I need to add another tool to my toolkit.

Thanks for everyone’s input on this topic…
