The external miners trigger some antivirus false positives because miners are sometimes included in trojans used for botnets.
The windows wallet was cross-compiled from linux, and I verified that the .exe files downloaded from sourceforge are exactly the same that were generated by my ubuntu. So unless it's a new kind of linux/windows supervirus then it's clean.
If you have your doubts, compile it yourself. That's the beauty of gitian: you can verify the binaries.

I have built the source from scratch and it is all fine. Stop FUD'ding and get mining.
Gatra, this is bloody hard to mine. The estimated time to block seems wildly off though, its maybe 10 time longer IMO
