While installing "Pristine Sound 2005" (a mp3 audio editor) on my Windows 7, "ZT" desktop PC, my Trend Micro Maximum Security flagged and deleted a file named hardshell.exe, reporting that it was suspicious and associated with the virus HEU_AEGISCS901T. Now the Pristine Sound 2005 application will not start without this file. My associates install and run this software with no problems but I'm afraid to override Trend. I need to know if this is a false positive because I need this software. Can you please help.
