According to the signatures of BitDefender, it is a toolbar Trojan.
CursorMania allows the user to change the appearance of their cursor, from a range of swords, animals and even religious culture.
CursorMania's popularity came from a video from YouTuber and Live Streamer Vinesauce Joel, who downloaded the trojan for his video "[Vinesauce] Joel - Windows 7 Destruction" which was uploaded on the 13th September 2014 and has around 3,500,000 views as of April 2018.
CursorMania, when downloaded, adds a toolbar on to the user's browser. It affects browsers like Internet Explorer, Opera and Mozilla Firefox. When the toolbar is added, it gives the user a trojan and usually makes the cursor disappear and slow down the computer. If the user has Opera or Internet Explorer the user will be added to a botnet called DragonDog, that will change the home page to a fake page that is similar to the original page.
There have been different ways to change the appearance of a cursor, but CursorMania was one of the more popular ways, despite being the least effective.
The toolbar would connect you to a Netbot called DragonDog, which would affect browsers like Internet Explorer to change the user's homepage to fake YouTube and Facebook websites, Club Penguin and PC Optimizer Pro.
The removal process its actually very easy, you just only need to download a anti-virus and it will do all the job, if you don't want, then you can try to uninstall it from the Control Panel of Windows.
