CloudFront removal instructions

What is CloudFront?

CloudFront is a legitimate service provided by Amazon allowing developers to improve users' web browsing experience by optimizing distribution of certain web content (read more here). Cyber criminals abuse this service to promote various web scam models and malicious programs (e.g., fake Adobe Flash Player updater). If you continually encounter pop-ups that open with the cloudfront.net URL, your computer is probably infected with a type of malware (most likely adware or a browser hijacker).

CloudFront adware

As mentioned above, CloudFront service is used by cyber criminals who typically promote various websites that display fake errors. This scam model is very simple - users visit a deceptive website and encounter a fake error message, often stating that the system is damaged (e.g., infected, missing files, or similar). Users are then encouraged to contact "certified technicians" (via telephone numbers provided) to resolve these issues. Be aware, however, that these pop-up errors are false - rather than calling technical support, users will be contacting cyber criminals who claim to be the technicians. Users are then encouraged to pay certain fees in exchange for 'help' in removing infections or returning their systems to normal. In some cases, users are asked to grant remote access to their computers. Once connected, criminals stealthily install malware and change system settings, after which they claim to 'detect' additional issues and offer further help for an extra fee. There is also a high probability that these people will demand answers to various "Yes/No" questions. They do this to record positive responses and use them as 'proof' that victims have agreed to submit various payments (e.g., online purchases, credit card charges, or similar). In addition, these fake-error-displaying websites are designed to appear legitimate (for instance, they contain Apple/Microsoft logos, etc.) and so they might seem believable, however, operating system developers do not use websites to inform users of corrupted systems, infections, and so on. Criminals also employ CloudFront to promote websites claiming that the system is running outdated software. The most common is Adobe Flash Player. In fact, rather than downloading Flash Player updater, users will download high-risk malware (e.g., password stealers, keyloggers, etc.) If you are continually redirected with the cloudfront.net URL, immediately eliminate all dubious programs/browser plug-ins and scan the entire system with a legitimate anti-virus/anti-spyware suite.

Unwanted pop-ups are often delivered by adware/browser hijackers. Adware is a form of software that delivers various intrusive advertisements (coupons, banners, pop-ups, etc.) To achieve this, developers employ various tools (e.g., "virtual layers") that enable placement of third party graphical content on any site. Therefore, displayed ads conceal underlying website content, thereby significantly diminishing users' Internet browsing experience. Furthermore, intrusive ads typically redirect to malicious websites and even run scripts that stealthily download and install malware/PUPs. Therefore, even a single click can result in high-risk computer infections. Browser hijackers modify web browser options without users' consent. They assign browser settings (e.g., new tab URL, default search engine, homepage, etc.) to the URLs of malicious websites. As a result, users continually encounter unwanted redirects to these dubious sites. In addition, adware and browser hijackers gather various sensitive information (e.g., IP addresses, geographic locations, Internet service providers [ISPs], web URLs visited, pages viewed, search queries, keystrokes, etc.) that includes personal details. Developers sell this information to third parties (potentially, cyber criminals) who misuse private data to generate revenue. Therefore, the presence of data-tracking apps can lead to serious privacy issues or even identity theft.

Adware-type and browser-hijacking potentially unwanted programs (PUPs) often claim to provide various "useful features" (e.g., file conversion, system optimization, download performance increases, anti-virus software, and so on), however, rather than enabling any of the features promised, PUPs pose a direct threat to your privacy and Internet browsing safety. These programs are designed only to generate revenue for the developers.

How did potentially unwanted programs install on my computer?

To proliferate adware and browser hijackers, developers often use the aforementioned intrusive advertisements and, especially, a deceptive marketing method called "bundling". Therefore, due to lack of knowledge and careless behavior by many users, PUPs infiltrate systems without permission. "Bundling" is stealth installation of third party applications together with regular software/apps. Developers do not disclose these installations properly - they conceal "bundled" programs within various sections (e.g., "Custom/Advanced" settings) of the download or installation processes. Furthermore, many users rush these procedures and skip steps. In addition, they click suspicious links/ads without understanding the possible consequences. In doing so, they expose their systems to risk of various infections and compromise their privacy.

How to avoid installation of potentially unwanted applications?

This situation can be prevented by paying close attention when downloading/installing software and browsing the Internet in general. Firstly, select "Custom/Advanced" settings and carefully analyze each window of the download/installation processes. Decline offers to download/install additional applications and opt-out of those already included. Secondly, download your applications from official sources only and, preferably, using a direct download link. Third party downloaders/installers are monetized by promoting rogue apps (the "bundling" method) and, therefore, should never be used. Intrusive ads are designed to look legitimate. Once clicked, however, they redirect to gambling, survey, pornography, and other dubious websites. If you encounter such ads, immediately remove all dubious applications and browser plug-ins. The key to computer safety is caution.
