Due to several of the utilities that are included in the UBCD4Win, many times a year several AV vendors accidentally detect trojans and such when there is none. Another thing that pops up is that some files are flagged as hacktools and some people confuse that for trojans as well. Not that you have, just a info statement.
As Constance mentioned, if in doubt double check the hash before running to double check it has not been tampered with. If it says exactly what file is offensive, you can upload the file to http://virusscan.jotti.org/
and have it check the file against all the other AV vendors out there. Sometimes it is just one that flags that file and sometimes several vendors flag the file. It is a good benchmark to test the file.
