I am evaluating NOD32 using the trial version and also have AVG installed on the computer. AVG performed its scheduled scan and informed me that two zip files contained Trojan Horse Downloader.Small.19.D. I did a scan of NOD32 using Windows explorer and it showed no infection whatsoever. I also did a scan using virusscan.jotti.org and only AVG and AntiVir found anything in the two files. Sorry but I no longer have the two files as they have been deleted.
