Ultimate Scan

Ultimate Scan Description

Ultimate Scan is a fake anti-malware program designed to convince computer users to buy its full version. Ultimate Scan does this by pretending to find numerous security problems on the infected computer, and then convincing the victim that a “full version” of Ultimate Scan must be bought to remove the imaginary problems. Our ESG team of PC security researchers has identified a large number of clones of Ultimate Scan, including Ultimate Guard, Unlimited Guard, Unlimited Defender, Clean Security, Malware Protection 2009, and Vista Anti-virus 2012. Having Ultimate Scan installed on your computer system is a serious security risk. This dangerous rogue anti-spyware program should be removed immediately with a real anti-malware program.

Ultimate Scan's Convincing Interface

Ultimate Scan is designed to mimic the design of Windows Security Center. The window layout is a copy of the Windows XP theme, and it uses the Microsoft and Windows official logos in several instances (the most prominent of these being a large Windows logo on the top left corner). On the left sidebar, the computer user will find a number of options. Our ESG PC security researchers advise you against trying these options out, they are all false. In the main window, there are several red warnings that will change to green if the computer user enters his credit card information to buy a “full version” of Ultimate Scan.

Effects of Ultimate Scan on an Operating System

Our ESG malware researchers have identified absolutely no anti-virus capabilities within Ultimate Scan. This program is little more than its convincing interface and a group of harmful Trojans and malicious scripts. Far from finding viruses on a computer, our ESG malware researchers have associated Ultimate Scan with a number of annoying computer problems. Some effects of Ultimate Scan include increased system instability, slowness, increased memory consumption, constant pop-up notifications, changes to the Internet browser settings, error messages when launching executable files, and other similar problems associated with rogue security programs.

Don't Fall for It, Say Good Bye to Ultimate Scan for Good

Our ESG team of PC security researchers recommends removing Ultimate Scan immediately. Ultimate Scan may include Trojans designed to spy on your Internet activity and relay it to a third party. Because of this, as long as Ultimate Scan is infecting your computer system, you should be aware that your passwords and personal information may have been compromised. Removing Ultimate Scan can be done with a fully-updated anti-malware tool. If Ultimate Scan is blocking your anti-malware program from opening, start up Windows in Safe Mode.
