I just installed the free edition of Bitdefender and it doesn't seem to be willing to do anything at all. I have Windows 7 and have used other Antivirus programs without an issue, but when I right clicked on my C drive, as well as several other folders to do a scan Bitdefender added them to a queue and then just sat there. I cannot find anything in the limited interface that seems to make it do anything at all. What am I supposed to do to actually make this work?
