According to my antivirus software latest release of litecoin core 0.17.1 @litecoin.org is infected by trojan!
I am going to install..before I do...to compare..what software are you using?
I'm using Avast Pro...anyway, we will see how that acts as I install and probably won't know till i updates for the last month
will let folk know on here if it is good to go or not with Avast Pro.
edit:
Just installed Litecoin Core 0.17.1 with no issues using Avast Pro! So no issues here with me, (so far)

Just an FYI.
