Around a week ago, i downloaded GUIMiner-scrypt from the download link on https://bitcointalk.org/index.php?topic=150331.0

However, now when i run a Malwarebyte scan, this is telling me the downloaded file (extracted files), and my chrome browser is now infected with:

• PUP.BitCoinMiner
• Trojan.BtcMiner.TS
• PUP.Proxy.BCM
  

Are these false positives, or are these something i need to worry about and remove?

Thanks
Ford
