How may i fix Memory Leak of league

I have this problem for my league client which freezes my mouse and the screen. Which i had tried to use my webroot security program to check my software program and i have this memory leak of leagueclientux.exe which i tried to ask from help from the geek squad, which they asked me to pay 39.99 just for that shit which i think i would to be able to fix that thing so. Then I went to the webroot tech support which takes forever which i have waited and they still don't help the customers. Please i need help to fix this client.
