I have had the NC Soft Launcher on my system since the day it was released. I use it to launch City of Heroes. A few days ago, I added Lineage II through the NC Soft Launcher because that was the recommended installation procedure. Today my anti-virus warned that a Trojan (Win32.Swisyn.cedt) was downloaded and installed on my system through a Lineage II update installed by the NC Soft Launcher. Naturally I ran the removal and restoration procedure supplied with my anti-virus program.
Before people start throwing accusations around. I am simply reporting the facts that my anti-virus program has reported to me.
