Hey Midnight Blues,
I did install today cGPSmapper v0099b Routable release from Team ROGUE on my Vista x64 PC. However although my McAfee VirusScan Enterprise did not see anything, my (free) firewall Windows 7 FireWall Control from SphinxSoftware (sphinx-soft.com) did catch the patcher Patch.exe trying to get on the internet ... Hence it must contain a Trojan ... Therefore it is better to have a functioning FireWall or to disconnect from the internet while installing ...
Well, the Keymaker.exe file appears to be safe ...
