Technically, 'Nattly' is not a virus or malware, however, it is categorized as a potentially unwanted application or adware. It is similar to other browser toolbars (which install without users' consent and modify browser homepages and default search engine settings). Examples include Babylon, Delta Search, SearchGol, and many others. Note: this toolbar installs together with 'Bit Guard', a small program that disallows changes by the user to the homepage or default search engine.

This behaviour is similar to malware infections. As mentioned, the most common source of unwanted browser toolbars is free software downloads, and therefore, to avoid installation of the Nattly toolbar or any other adware, be attentive when downloading and installing freeware.

In addition, when installing freeware, always choose the 'Custom' or 'Advanced' installation options - this will reveal any hidden (bundled) browser plugins.
