Yep i dont think its a virus at all.
Overheating also no.
Basically for the past 1.5 hours i have downloaded like 700MB by turning the launcher on, waiting for the connection to drop and usually getting somewhere from 50 - 200 MB downloaded before my laptop looses connection.
Then i restart my laptop and try again...
the router actually is not the issue... the laptop's internet connection just fails and then when i try to disconnect and reconnect it doesn't. So I restart and it magically connects back just fine.
