Windows Custodian Utility

Windows Custodian Utility Description

Type: Possibly Unwanted Program

ScreenshotESG security researchers have released an alert about Windows Custodian Utility, a fake security program that may be installed voluntarily or appear on the victim's computer without their consent. Windows Custodian Utility is not a real security application and is part of a malware attack on the infected computer system. Windows Custodian Utility is one of the many fake anti-virus programs belonging to the FakeVimes family of malware. These kinds of malware applications are known as rogue anti-virus programs. Malware in Windows Custodian Utility's family has been around for several years (at least since 2009), and new versions of these fake security applications are released periodically.

Examples of clones of Windows Custodian Utility include Virus Melt, Presto TuneUp, Fast Antivirus 2009, Extra Antivirus, Windows Security Suite, Smart Virus Eliminator, Packed.Generic.245, Volcano Security Suite, Windows Enterprise Suite, Enterprise Suite, Additional Guard, PC Live Guard, Live PC Care, Live Enterprise Suite, Security Antivirus, My Security Wall, CleanUp Antivirus, Smart Security, Windows Protection Suite, Windows Work Catalyst.

There are dozens of versions of FakeVimes rogue anti-virus programs, all of them composed of the same basic program with a different name and differently-named components (such as file names). Criminals create these clones in order to make it more difficult for malware analyst to identify Windows Custodian Utility clones for what they are. Malware in the FakeVimes family is characterized by its use of randomly-named files, composed of a three-letter string which is entirely random. This string is often preceded with the sting "protector-" or "inspector-" depending on the particular clones of Windows Custodian Utility attacking the victim's computer system.

Understanding How Criminals Use Windows Custodian Utility to Steal Your Money

Windows Custodian Utility is not very different from most rogue anti-virus applications. These are all characterized by using the same basic scam: entering a victim's computer, claiming to be a legitimate security program, and then deliberately causing problems on the victim's computer in order to convince the victim to purchase a "full version" of Windows Custodian Utility. ESG security researchers have not detected any anti-malware capabilities within Windows Custodian Utility, and it is certain that this fake security program is part of this well-known online scam. Basically, Windows Custodian Utility is designed to do little more than display several error messages and misleading security alerts, and to direct the victim constantly to a website which will prompt them to enter their credit card information so as to purchase this useless "full version" of Windows Custodian Utility. You should not purchase Windows Custodian Utility under any circumstances; remove Windows Custodian Utility with a reliable anti-malware program instead.
