What kind of software is HTTP Error Decoder?
Our researchers discovered the HTTP Error Decoder browser extension while inspecting untrustworthy websites. It is promoted as a tool that eases navigation in error-prone sites.
After examining this rogue extension, we determined that it is advertising-supported software (adware). HTTP Error Decoder is designed to generate revenue for its developers by feeding users with unwanted and potentially malicious advertisements.
HTTP Error Decoder adware overview
Adware runs intrusive advertisement campaigns. It displays ads (e.g., pop-ups, overlays, coupons, banners, surveys, etc.) on visited websites and/or other interfaces.
Note that this software might not run intrusive advert campaigns if certain conditions are unsuitable (e.g., incompatible browser/system or user geolocation, specific sites not visited, etc.). However, regardless of whether HTTP Error Decoder delivers advertisements – it endangers device/user safety.
Not only does the third-party graphical content displayed by adware diminish the browsing experience and/or system performance, but it also promotes online scams, unreliable/harmful software, and malware. When clicked on, some intrusive adverts can even execute scripts to perform downloads/installations without user permission.
It is pertinent to mention that while legitimate products or services may be encountered via these ads – they are unlikely to be endorsed in this manner by any official parties. It is most probable that this promotion is undertaken by scammers who abuse the content's affiliate programs in order to obtain illegitimate commissions.
Furthermore, HTTP Error Decoder spies on users' browsing activity. Data of interest may include: browsing and search engine histories, Internet cookies, usernames/passwords, personally identifiable details, finance-related information, etc. The collected data can then be sold to third-parties or otherwise abused for profit.
To summarize, advertising-supported software like HTTP Error Decoder can cause system infections, serious privacy issues, financial losses, and even identity theft.

Software within this classification typically appears genuine and harmless. It also offers a wide variety of useful functionalities, which are rarely operational. It must be stressed that functional features are not a guarantee of a software's legitimacy or safety.
How did HTTP Error Decoder install on my computer?
We obtained HTTP Error Decoder from its "official" download webpage. In addition to such legitimate-looking pages, adware is promoted on scam websites.
Most visitors access these webpages via redirects generated by sites using rogue advertising networks, mistyped URLs, spam browser notifications, intrusive ads, or installed adware (with browser force-opening abilities).
Advertising-supported software can also be bundled with ordinary programs. Downloading from dubious channels (e.g., freeware and free file-hosting websites, Peer-to-Peer sharing networks, etc.) and treating installations with negligence (e.g., skipping steps, using "Easy/Express" settings, etc.) – increase the risk of allowing bundled content into the system.
Intrusive advertisements spread adware as well. Some of the adverts can execute scripts to perform stealthy downloads/installations upon being clicked.
How to avoid installation of adware?
We highly recommend researching software and downloading it only from official/trustworthy sources. Installation processes must be treated with care, e.g., by reading terms, exploring possible options, using the "Custom/Advanced" settings, and opting out of all additional apps, extensions, tools, etc.
Another recommendation is to be careful while browsing since fake and malicious online content usually appears legitimate and harmless. For example, intrusive advertisements may look ordinary/innocuous – however, they redirect to highly questionable sites (e.g., gambling, adult dating, pornography, etc.).
In case of encounters with such adverts and/or redirects, inspect the system and immediately remove all suspicious applications and browser extensions/plug-ins. If your computer is already infected with HTTP Error Decoder, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this adware.
