Exactly what the title says. I've been using my gaming rig for torrenting and it now occasionally starts lagging everyone else in the house when I turn it on or connect to the internet. It always eventually goes away but eventually comes back as well. Also it isn't just them lagging because I do also and I was wondering if it was some sort of virus. I've heard of torrents that make your computer into a bit miner but I'm not sure if that's really the case
