Ignore the "Required video codec is not installed on your computer" scam

What is "Required video codec is not installed on your computer"?

Blue screen of death (BSoD) is an error screen that appears when the Windows Operating System can no longer operate. This website loads a fake BSoD stating that Windows Media Player cannot play a video because the required video codec is not installed on the operating system.

It is very likely that this web page is used to trick visitors into downloading and installing a potentially unwanted application (PUA). At the time of research, this social engineering scam distributed ZLoader malware. Note that this web page is promoted via fake movie streaming websites, which users do not visit intentionally.

This deceptive web page claims that a video cannot be played without the correct video codec. It states that visitors can install the codec by downloading and executing a specific file. In fact, it is very likely that this site is used to trick users into installing an adware-type app, browser hijacker, or other unwanted/malicious application.

Adware-type apps serve coupons, surveys, banners, pop-ups, and other types of advertisement. If clicked, these open dubious websites or even cause download/installation of unwanted software by executing certain scripts. Browser hijackers change certain browser settings to the address of a fake search engine.

Most adware-type apps and browser hijackers collect browsing data such as, for example, IP addresses, geolocations, entered search queries, addresses of visited websites and other information relating to users' browsing habits. In some cases, they are capable of gathering private, sensitive details as well.

Some examples of other, similar web pages are "Killer's IP Address", "Google Chrome Blocked For Security Reasons" and "Windows Error Code: WIN.DLL0151930". Note that these pages are used users to trick people into paying for unnecessary software and services, and even into giving scammers remote access to their computers.

Therefore, avoid these websites. If they are opened by a browser often, it is likely that the browser has a PUA installed.

How did potentially unwanted applications install on my computer?

Browser hijackers, adware-type apps, and other types of PUAs are commonly distributed by integrating them into the download and/or installation set-ups of other programs, so that a proportion of users inadvertently download and install them together with their chosen software.

This distribution method is known as "bundling". Offers to download and install additionally-included apps usually appear in "Advanced", "Custom" and other settings of the set-ups (where they can usually be declined). Many users fail to check and change these settings, thereby granting permission for PUAs to be downloaded and installed by default.

In addition, unwanted downloads and installations are sometimes caused by clicking deceptive advertisements capable of executing certain scripts.

How to avoid installation of potentially unwanted applications

You are advised to download files and programs from official websites and via direct download links. Other tools and sources such as third party downloaders and installers, unofficial pages, and Peer-to-Peer networks (e.g., eMule, torrent clients) should not be used to download or install software.

Check all "Custom", "Advanced" and other similar settings (or available checkboxes) for offers to download and/or install unwanted apps. Do not click ads on dubious websites, since they can be designed to open bogus web pages or cause unwanted downloads and installations.

Remove any unwanted, suspicious extensions, plug-ins and add-ons installed on the browser, and software of this kind from the operating system. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
