After the installation, open your antivirus and then go to its settings.

After that before installing the new client, disable your antivirus first so it won’t be scanned by the antivirus. If you are still using the game client before and haven’t checked for any new version, it would be best to visit the game’s official website and then download any new release of the game client including any patches if there are any. But there is still a way of getting around this problem by excluding your game client from the files being monitored by your antivirus.īut first since your program no longer works, uninstall it again from your computer.

It seems that after you allowed your antivirus to remove that suspected malware in your computer, it is now preventing your game client from gaining any outside connection because of the error you are getting in your internet connection. This happens because of the activity detected in the file while it is processing. This is normal actually for an antivirus to accidentally detect a program as a malware. I think too, your antivirus mistakenly identified your game client as a virus. League of Legends Launcher connection error to HTTP Servers
