When I enter activation code for Free Studio (Free Youtube Download specifically?)Bitdefender goes nuts and ID's files as av or malware (?) and quarantines a bunch of files. I Immediately reinstall last image and have the free studio (DVDVIDEOSOFT) program but would like to get the paid version to download and convert to mp3 from youtube. BD can be a pain! Any workaround for this? I did get a refund so it's not all bad. I had used Free studio premium a few yrs back before BD.
