UniDueealssi (also known as UniDeals, UNiDealse, UniDeaalsa, UniDeaals a, UeniDeealsa, UniDeallsi) is deceptive adware and a potentially unwanted program (PUP) that serves pop-up and targeted advertisements across Google Chrome, Mozilla Firefox, and Internet Explorer by utilizing multiple browser attachments and programs that infiltrate a computer system without user knowledge. UniDueealssi additionally creates new tasks and is scheduled to run every time Windows starts.


Furthermore, the UniDueealssi virus (although not technically a computer virus) is difficult to completely remove. Once the UniDueealssi extension is manually removed and the browser window is closed, the extension will reappear the next time the browser window is opened. The browser attachment also runs in developer mode which allows it to gather and edit personal information and internet settings.
