Hi
I expected BitDefender to find & delete all those files in the Symantec quarantine folder, but it didn't see any ...
Have another look in the Symantec AntiVirus\Quarantine folder & see if it's now empty ?
I've had a look at the file you uploaded, I don't see anything suspicious in it, it appears to be something related to a blues album called StrawbAiry Soul ? possibly a file generated during a burn/copy operation ? ... anyway I don't see it as a problem.
