In my v.109 installation, the only files that are identified by Eset NOD32 Antivirus, which is supposed to be a pretty good antivirus program, are
C:\\Program Files\\ArcSoft\\TotalMedia Theater\\Plugins\\VideoModule\\PlayDVD\\UI\\Media_01.aui
C:\\Program Files\\ArcSoft\\TotalMedia Theater\\Plugins\\VideoModule\\PlayDVD\\UI\\Media_02.aui
Each is identified as a "Themida application" by Eset and they have been identified on the ArcSoft Forum as legitimate parts of the TMT installation. ArcSoft reports that hackers have used these file names for malware, but the TMT files are legitimate. These files will be quarantined by NOD32 and I don't believe TMT runs if these files are quarantined, although I could be mistaken about that.
