WinFixer[a] was a family of scareware rogue security programs developed by Winsoftware which claimed to repair computer system problems on Microsoft Windows computers if a user purchased the full version of the software. The software was mainly installed without the user's consent.[1] McAfee claimed that "the primary function of the free version appears to be to alarm the user into paying for registration, at least partially based on false or erroneous detections."[2] The program prompted the user to purchase a paid copy of the program.[3]

The WinFixer web page (see the image) said it "is a useful utility to scan and fix any system, registry and hard drive errors. It ensures system stability and performance, frees wasted hard-drive space and recovers damaged Word, Excel, music and video files." However, these claims were never verified by any reputable source. In fact, most sources considered this program to actually reduce system stability and performance. The sites went defunct in December 2008 after actions taken by the Federal Trade Commission.

Installation methods

[edit]
An example of a WinFixer pop-up dialog box within Opera. Even if the Cancel or Close buttons were clicked to dismiss the box, it would redirect to a WinAntiVirus page anyway, featuring a fake system scan.

The WinFixer application was known to infect users using the Microsoft Windows operating system, and was browser independent. One infection method involved the Emcodec.E trojan, a fake codec scam. Another involves the use of the Vundo family of trojans.[4]

Typical infection

[edit]

The infection usually occurred during a visit to a distributing website using a web browser. A message appeared in a dialog box or popup asking the user if they wanted to install WinFixer, or claimed a user's machine was infected with malware, and requested the user to run a free scan. When the user chose any of the options or tried to close this dialog (by clicking 'OK' or 'Cancel' or by clicking the corner 'X'), it would trigger a pop-up window and WinFixer would download and install itself, regardless of the user's wishes.

Initial message prior to infection - a user wishing to avoid infection might wish to disconnect from the Internet before closing the dialog box.

"Trial" offer

[edit]

A free "trial" offer of this program was sometimes found in pop-ups. If the "trial" version was downloaded and installed, it would execute a "scan" of the local machine and a couple of non-existent trojans and viruses would be "discovered", but no further action would be undertaken by the program. To obtain a quarantine or removal, WinFixer required the purchase of the program.[5] However, the alleged unwanted bugs were bogus, only serving to persuade the owner to buy the program.

WinFixer application

[edit]

Once installed, WinFixer frequently launched pop-ups and prompted the user to follow its directions. Because of the intricate way in which the program installed itself into the host computer (including making dozens of registry edits), successful removal would have taken a fairly long time if done manually. When running, its process could be found in the task manager and be stopped, but would automatically relaunch itself after a period of time.

WinFixer was also known to modify the Windows Registry so that it started up automatically with every reboot, and scanned the user's computer.[6]

Firefox popup

[edit]

The Mozilla Firefox browser was vulnerable to initial infection by WinFixer. Once installed, WinFixer was known to exploit the SessionSaver extension for the Firefox browser. The program caused popups on every startup asking the user to download WinFixer, by adding lines containing the word 'WinFixer' to the prefs.js file.

Removal

[edit]

Removal of WinFixer proved difficult because it actively undid whatever the user attempted. Frequently, procedures that worked on one system would not work on another because there were a large number of variants. Some sites provided manual techniques to remove infections that automated cleanup tools could not remove.[7]

Domain ownership

[edit]

The company that made WinFixer, Winsoftware Ltd., claimed to be based in Liverpool, England (Stanley Street, postcode: 13088.) However, this address was proven to be false.[8]

The domain WINFIXER.COM on the whois database showed it was owned by a void company in Ukraine and another in Warsaw, Poland.[9] According to Alexa Internet, the domain was owned by Innovative Marketing, Inc., 1876 Hutson St, Honduras.

According to the public key certificate provided by GTE CyberTrust Solutions, Inc., the server secure.errorsafe.com was operated by ErrorSafe Inc. at 1878 Hutson Street, Belize City, BZ.

Running traceroute on Winfixer domains showed that most of the domains were hosted from servers at setupahost.net, which used Shaw Business Solutions AKA Bigpipe as their backbone.

Technical information

[edit]

Technical

[edit]

WinFixer was closely related to Aurora Network's Nail.exe hijacker/spyware program. In worst-case scenarios, it would embed itself in Internet Explorer and become part of the program, thus being nearly impossible to remove. The program was also closely related to the Vundo trojan.[4][10]

Variants

[edit]

Windows Police Pro

[edit]

Windows Police Pro was a variant of WinFixer.[11] David Wood wrote in Microsoft TechNet that in March 2009, the Microsoft Malware Protection Center saw ASC Antivirus, the virus' first version. Microsoft did not detect any changes to the virus until the end of July that year when a second variant, Windows Antivirus Pro, appeared. Although multiple new virus versions have since appeared, the virus has been renamed only once, to Windows Police Pro. Microsoft added the virus to its Malicious Software Removal Tool in October 2009.[12]

The virus generated numerous persistent popups and messages displaying false scan reports intended to convince users that their computers were infected with various forms of malware that do not exist. When users attempted to close the popup message, they received confirmation dialog boxes that switched the "Purchase full version" and "Continue evaluating" buttons.[12] Windows Police Pro generated a counterfeit Windows Security Center that warned users about the fake malware.[13]

Bleeping Computer and the syndicated "Propeller Heads" column recommended using Malwarebytes' Anti-Malware to remove Windows Police Pro permanently.[12][14] Microsoft TechNet and Softpedia recommended using Microsoft's Malicious Software Removal Tool to get rid of the malware.[12][15]

Effects on the public

[edit]

Class action lawsuit

[edit]

On September 29, 2006, a San Jose woman filed a lawsuit over WinFixer and related "fraudware" in Santa Clara County Superior Court; however, in 2007 the lawsuit was dropped. In the lawsuit, the plaintiffs charged that the WinFixer software "eventually rendered her computer's hard drive unusable. The program infecting her computer also ejected her CD-ROM drive and displayed Virus warnings."[16][17][18]

Ads on Windows Live Messenger

[edit]

On February 18, 2007, a blog called "Spyware Sucks" reported that the popular instant messaging application Windows Live Messenger had inadvertently promoted WinFixer by displaying a WinFixer advertisement from one of Messenger's ad hosts.[19] A similar occurrence was also reported on some MSN Groups pages. There were other reports before this one (one from Patchou, the creator of Messenger Plus!), and people had contacted Microsoft about the incidents. Whitney Burk from Microsoft issued this problem in his official statement:

Microsoft was notified of malware that was being served through ads placed in Windows Live Messenger banners. As a result of this notification we immediately investigated the reports and removed the offending ads, as this is a violation of our ad serving policy. We can confirm that the ads are no longer being served by any Microsoft system. We apologize for the inconvenience and are reviewing our ad approval process to reduce the chance of an occurrence such as this happening again. To help customers protect their PCs from malware threats, Microsoft recommends customers follow our Protect your PC guidance at www.microsoft.com/protect.

— Whitney Burk, Microsoft

Federal Trade Commission

[edit]

On December 2, 2008, the Federal Trade Commission requested and received a temporary restraining order against Innovative Marketing, Inc., ByteHosting Internet Services, LLC, and individuals Daniel Sundin, Sam Jain, Marc D’Souza, Kristy Ross, and James Reno, the creators of WinFixer and its sister products. The complaint alleged that the products' advertising, as well as the products themselves, violated United States consumer protection laws.[20] However, Innovative Marketing flouted the court order and was fined $8,000 per day in civil contempt.[21]

On September 24, 2012, Kristy Ross was fined $163 million by the Federal Trade Commission for her part in this.[22][23] The article goes on to say that the WinFixer family of software was simply a con but does not acknowledge that it was in fact a program that made many computers unusable.
