how to autorun again avast

good day!
how to autorun again avast? I accidentally disable it on msconfig. i try to autorun it by checking avast on msconfig. after applying changes and reboot, avast still don’t autorun.

how to solve this?

one more thing, i’m just wondering why avast still scans mp3s, avis, mpeg, jpg, etc. etc. that i’ve already set not to scan it.

thanks!

Try repair avast going Add/Remove Programs>Avast>Repair

What did you set to avast does not scan them?
