What is Windows Ultra Antivirus?

Windows Ultra Antivirus is a fake antivirus program, which uses trickery in order to sell its useless license key to unsuspecting PC users. This program is an imitation of a legitimate computer security scanner and the processes displayed by Windows Ultra Antivirus are falsely-generated (fake). This malicious software mimics the detection of security infections - the results identical on all computers infiltrated. Cyber criminals created this rogue program in the hope that you will believe the bogus security warning messages and purchase a full version of this software in order to eliminate supposed security issues. This bogus software is distributed via security vulnerabilities in users' PCs - Cyber criminals set up misleading websites to exploit these vulnerabilities and install Windows Ultra Antivirus without consent. Often, this rogue antivirus program imitates a critical Windows update. The landing page, used by Cyber criminals to install this scam, appears like the genuine Windows update website - asking to install the 'Windows Malicious Software Removal Tool (Critical Update) - February 2011 (KB990831)'.

Commonly, fake antivirus programs are grouped into rogue families, however, this software does not seem to derive from any previously-known families. In order to make Windows Ultra Antivirus rogue complicated to eliminate, Cyber criminals have bundled this scam with a rootkit, which protects the registry entries and processes of the fake security scanner. To successfully remove Windows Ultra Antivirus from your computer, you need to remove the rootkit infection. When installed on your PC, this bogus software uses various deceptive messages in an attempt to coerce you into buying a license key. This fake software reports that 'Your computer is not protected' and constantly interrupts you with similar pop-ups, such as 'Security Warning! Your computer is not checked for viruses! System scan is recommended. Press "scan" to check'. Do not believe these messages, it is a scam.

Do not pay for this software - you will send your money to cyber criminals and your computer will remain infected. The statements asserting that your computer does not have 'Antivirus and Antispyware protection', 'Proactive Threat Protection', and 'Network Treat Protection', plus the 'detected security infections' list, are created to scare you into believing that your PC is at risk. In fact, none of the security threats indicated by Windows Ultra Antivirus exist on your computer. Ignore this malicious software and use the removal guide provided to eliminate it from your PC.
