We are getting reports of Google Chrome blocking both dBpoweramp R15 and PerfectTUNES R2, google chrome reports these files are malicious. Note neither of these programs have ever contained a virus, malware, or other nasty.
Sadly google do not have a reporting function so there is little we can do to redress this issue except that to advise you to use a different browser to download.
** Update, it is only older versions of chrome which are blocking, perhaps Chrome is blocking all downloaded programs because it is out of date. Update to the latest Chrome to fix the issue **
