they ask you if you would like to install it.Quote:
Avira said that installed for me "MinerSoftware.exe", which basically makes me BitCoin miner slave.
If u really want to support you by something like that, ask users. I would let it mining, but not when I cannot control this.
I think that is the reason, why you guys got FPS drops. BitCoin mining program using a lot of computer resources. Mainly GPU, which "makes" your FPS.
