Shareaza

There is probably a setting that I have to check or uncheck, but here goes....

Whenever I am just on the internet and find a program that I want to download and save to my computer, the shareaza program comes up. Why is that? I should be able to download anything and not have to use shareaza.

Shareaza have some atributes of malware

"Use Shareaza to mange all my web downloads" I think is the one to uncheck.
On the "Web" tab in settings.
