What Is It?
Minibug / Weatherbug - minibugtransporter.dll
What Does it Do?
Minibug / Weatherbug isn't a major concern but it does has some potential privacy related things that you should be aware of. They do collect personally identifiable information. You will want to read over the EULA. A form of adware called My Search will also be installed on your system. You do get something decent out of this deal since you get reliable weather updates. If it weren't for the privacy issues and adware this would really be a nice program.
