Hmtoolbar is a hijacker that is implemented as an Internet Explorer browser helper object. This spyware will add toolbars to your Internet Explorer browser and even displays advertisements on your computer. This nuisance will then download additional third-party software onto your PC.  To top it all off, this is all done without your consent.
This software is installed manually so it most likely was installed onto your computer bundled with other software.  This malware will slow down your computer and make it difficult to function properly.  It is highly recommended that you remove this software with a trusted anti-spyware program such as SpyZooka.  SpyZooka has the experience and reputation for ridding users of their spyware problems.
