Disabling Programs/ Addons

[jetsmell 45]

When flying my PMDG 737, FSX will prematurly end the flight.It goes back to the beginning when it first starts up. My question here is ; Since the PMDG is so demanding would it be wise to disable my AVG Anti-virus, some addons not being used, like Cumulus X, Winch X( only used when flying my glider) Mega Scenry (Oh. and Ky. ) etc. What do you guys do? Where do I go to disable NOT un-install? Thanks in advance!

You can disable  your  avg   but  you can also in the option in avg   settings  to exclude  scanning  of  your  fsx  as well
