Just fyi .. another download of the file from mirror 7 showed again in symantec, this time with a PUP/PUA (potentially unwanted program / potentially unwanted app)
That the infector changed from one attempt to the next, suggests something is dynamically interfering with the file.
I've seen other users report issues in the past and I believe its not IMGBurn's intent, but that something is definitely wrong if this is happening to more than just one or two people ... dependent on the link clicked.
Also in this screen shot, note it says the file is 22 days old.. yet this version was last updated in 2013 so why would we be seeing the discrepancy?
Hopefully you'll have enough to test and find if there is an issue.
