So I opened up league today and it had an update. So as it was installing, my antivirus alerted me that a file called Pua.Safe.Install was inside the update. My antivirus removed it and I tried re-downloading the update. Unfortunately, it kept popping up with an error. I restarted my computer and I uninstalled league of legends from my computer. I waited a bit and reinstalled it, only for it to say there was another error.
Please let me know if this is something with the alpha client or if its my computer itself.
