Note ---- This May or may not work to counter the "virus" picking up by avg, only worked once for me but you guys may have a chance!
Step 1) Open AVG
Step 2) Click Tools and go down the list to "Advance Setting..."
Step 3) Move dwon the list to "Allow List"
Step 4) Click "Add"
Step 6) Find the file you want to add and then click "Add'' again
Step 7) You'r Done!!
Reminder This may or may not work to prevent the fake "virus", I hear that the game staff are trying to solve the problem for good. So this is only a temp solve, If this dose not work then Disable avg for 5minutes open the client and then enable avg again whent he client is open. Then your good!
