- Norassie and similar PUPs may alter text on the Web pages visited by the computer user. A typical tactic used by these components will be to change words on a Web page into hyperlinks, which would lead the computer users to other websites containing questionable and frequently possible unsafe content.

How Norassie may be Installed on a Computer
The most common method of distributing Norassie is by bundling it with other software. When computer users install a new program, they may skip through the installation process, failing to realize that they also have agreed to install Norassie, unwanted Web browser toolbars, and other questionable add-ons. Once Norassie is installed, its main purpose is to generate ad revenue. To do this, Norassie displays ads frequently and makes changes to the affected Web browser that are designed to increase the likelihood that the computer users will click on ad content or visit certain URLs repeatedly. This large number of ads, redirects, and other unwanted behaviors can make a computer affected by Norassie to become extremely difficult to use as normal. It also may reduce the system performance and increase the likelihood of a threat infection or more serious problems down the line. Norassie is an entire family of adware and PUPs that are signed by Norassie LTD, based on Mahe, Eden Island. This company has been known for distributing other adware and PUPs, using the digital signature associated with COMODO CA Limited. It is crucial to take care when installing any new software to prevent unwanted components like Norassie from being bundled along with any new software.
