Trojan found in Avast

Malwarebytes’ found this Trojan.Agent.UPX in the latest version of Avast in C:\Program Files\Avast Software\Avast\setup\Instup.dll. What’s up with having a virus in AVAST ANTI-VIRUS!!! Can anyone explain this?

Old news and it is already solved.
It was a false positive from Malwarebytes.
