Well I never had this problem with earlier versions of Avast, more on this new version I’ve been noticing a certain slowness in opening programs (. Exe).
Generally when run then quickly opens the first aperture, but when the system is restarted or during a certain period of time, back to take some time to open certain programs (almost).
I’ve tried to correct the installation of the Auxiliary Avast and the problem seems to continue.
The solution I found was to disable this option:

With this option off everything works normal.
