Phazebar.dll is adware/spyware and it generally installs a toolbar or searchbar along with BHO. BHO is short for “Browser Helper Object.” A BHO is a DLL file that controls internet explorer. Both phazebar.dll and its BHO are often used by online advertisers to control internet explorer so that any searches done show only the results specified by the advertisers.

Many BHO’s install internet explorer toolbars as a way of controlling the application. Most BHO applications do not even need your permission to install and can be used maliciously to gather information on your surfing habits. Because may spyware and BHO’s are poorly written they can cause many different computer issues including corrupting system functions.

If your phaze dll files are registered on an internet explorer URL search hook, when you open internet explorer or try to use a search engine, the phaze dll files redirect the users search and the user is taken to an unwanted website. Phaze dll files that have been registered on a URL search hook redirect users to sites usually specified in advance although sometimes the phaze dll files perform their own search instead. Phaze dll files are used to bring users directly to a predetermined website while others show users only pre-specified search results to boost traffic to their websites for advertising purposes. BHO, which is usually also installed along with phaze dll files is a browser helper object that helps to extend control over windows explorer as well as internet explorer.

Spyware installed as a BHO along with phaze dll files are executed by internet explorer so they are not seen by the windows task manager and are automatically executed by windows explorer whenever windows is started up. BHO’s and phaze dll files are used by adware and spyware to control the IE homepage, show popup ads, and monitor the address bar as well as redirect the browser whenever the user performs a search.
