Jdownlaoder is by far the best download manager that I know of. If there is a youtube video that I like, I copy the url (ctrl c) and jdownloader grabs that link, and reveals the flash or mp4 format that you can download.
Here is the problem... Spyware blaster tends to scan and locate Jdownloader files it wants to remove thus causing jdownloader to not work.
I want to know if its actually a false positive (which I think it is).
WARNING! Before downloading, be sure to un-check access extra stuff they want you to download if you want to test it. They do a good job fooling you into donwloading other stuff (click advance, etc during install).
