Related to the notorious malware applications known as Security Antivirus and My Security Wall, Cleanup Antivirus uses scare tactics to trick users into paying for its software license. Cleanup Antivirus gets installed on the user’s system via Trojans that get downloaded from malicious websites along with fake video/audio codec packs or get downloaded on to the user’s system as an infected PDF file. Once installed, Cleanup Antivirus takes measures to prevent its removal by disabling Windows utilities such as Task Manager and Registry Editor. Cleanup Antivirus proceeds to perform a large number of fake security scans on the system, generating false reports which state that the computer is under threat from malware. It also generates an endless stream of fake warning pop-ups from the Windows taskbar. Meanwhile, Cleanup Antivirus repeatedly requests the user to purchase a license to the ‘full’ version of the software, claiming that the currently installed ‘trial’ version is insufficient to remove all the detected ‘threats’. It enforces this request through its GUI, through pop-ups and through the results of fake scans. However, it is important to note that this is a fake security application and therefore none of its versions are capable of properly scanning or cleaning any system.
