URGENT: Problem with update database virus 141023-1

Big problem since this morning with this update, Avast block exe files

For example, you cannot start the chrome browser, Avast turns the file “Chrome.exe”

No problem with this update…!!!

No problem for me either.

GG,
What OS/SP?
What exact version of avast?
Any other security (related software) installed? (or did you)
What is the exact message that avast shows?
