I found virus in my dos emu. This was a clean install, and the virus killer was fresh and totally free of virus. This was reported by V-buster: C:\BIN\SWSUBST.EXE -infection:HLLP C:\BIN\JOIN.EXE -infection:HLLP C:\BIN\SUBST.EXE -infection:HLLP C:\BIN\SWITCHAR.COM -infection:AUST_PARASITE
Fixed. 0.99.13-6 uses completely redone dos images.
