my lol will not open up

Avast just shut LOL down and won't let it launch saying it's dangerous software! wtf!

I had the same problem. Tried everything in http://forums.na.leagueoflegends.com/board/showthread.php?t=3330957

Try this!

All you have to do is go to C:\Riot Games\League of Legends\RADS\projects\lol_patcher\releases\0.0.0.50\deploy and run LoLPatcher

*If you deleted anything, restore it from your trash. (Make sure all your files are back on your computer)

*If you permanently deleted it (or uninstalled the game) then just don't worry! Just find and Right click on your league folder > C:\Riot Games\League of Legends. Go to previous versions and open up up a version from yesterday or a week ago then copy the entire folder back onto you computer. Replace everything.
