Personally if flying online no way would I turn off antivirus

That has got to be some of the worst advice I have read, no offense to you MH, many others had offered this advice for online gaming.
If offline flying is what you are asking about shut everything off!
FSAutoStart is awesome, the inital setup can be a pain but once that is done you can use the same profile for what ever program you wish

Tried CCleaner and it seemed to have got a lot of junk that my other program misses, of course it would probably pick it up is I got the paid version
