BHODemon 2.0

BHODemon 2.0: "Given that (a) BHOs can do absolutely anything to your system, and (b) they are often installed without your knowledge, there is a distinct potential for abuse by vendors. The problem is, until now you had no way of knowing which BHOs are on your machine, who put them there, and what they do. This is what BHODemon does - it lets you easily manage your BHOs, and tells you what each BHO on your system is doing."

This is a very cute tool. Especially given the latest security warnings on IE where a file posing as a gif can install a BHO on your system which will grab secure details from IE itself (such as credit card info) before they are encrypted - and you simply have to visit a site for the BHO to get installed.

Download the above tool and you can keep an eye on BHO's already on your system and also be notified of new BHO's attempting to install.
