Client issue

I think this is my first time using the boards ( dont remember if i have or not) but with the release of the new update i saw an possible issue. The updater would not start. It would have the logo with the little bar appear but the updater/starter/thingbeforeyoulogin would not appear. I found the fix by going into avast's virus chest and restoring "LoLPatcherUx.exe". open the updater and repair since there is a possibility of corruption in the files(happened to one of my brothers). This happened to 3 computers in our household so i thought someone might have this problem arise, it might be avast or league, just trying to help. And if anyone needs to know LolPatcherUx.exe was shown as "Win32:Dropper-gen[Drp}"

Edit: Turns out someone already solved this. Edit 2: If it looks LoL related restore it since i had this problem again but it was called something like lollauncher
