Where is that nc.exe file supposed to be ? (In some archive ?)
Couldn't find it in UBCD4.0 beta 1 ISO ...

Anyway if you carefully read the report you posted, it seems like it is not a virus but a remote administration tool.

Location of nc.exe

It is in the compressed UBCD4WINv30.exe as well as the extracted location of plugin\Network\netcat\files\nc.exe. Several flag it as a trojan and several don't.

1) wrong forum. You need to go see for that info.

2) That is not a trojan at all. It is a tool that is very valuable but could be used by the bad guys to do bad things. It gets flagged by most AV companies due to its possibly being used for bad things. It is one reason why i hate NAV as we use it here at work and it flags it here all the time. In all actuality, it is flagged as a grey malware but not as an actual virus. NAV by default deletes/quarantines the file until it is told to ignore files like that.
