Watch out for Hidden Browser Helper Objects
A Browser Helper Object, or BHO, is a program that runs automatically every time you start your Internet browser. Usually, a BHO is installed on your system by another software program.
What do BHOs do? The answer is "anything", but generally, it will have something to do with "helping" you browse the Internet.
Many BHOs are "ad-ware" or "spyware": they do things like monitor the websites you visit and report this data back to their creators."
They often conflict with other running programs, causing such problems as page faults, run time errors, and slow down or hinder your surfing. As a matter of fact, I couldn't access certain parts of our on-line site-building software because I had a BHO on my system
One of the best tools for sniffing out, viewing and disabling BHOs is BHODemon.
