"Required video codec is not installed on your computer" removal instructions
What is "Required video codec is not installed on your computer"?
Blue screen of death (BSoD) is an error screen that appears when Windows operating system can no longer operate. This website loads a fake BSoD in it saying that Windows Media Player cannot play some video because the required video codec is not installed on the operating system. It is very likely that this page is designed to trick visitors into downloading and installing some potentially unwanted application (PUA) - at the time of research this social engineering scam was distributing ZLoader malware. It is worthwhile to mention that this page is promoted via fake movie streaming websites - users do not visit it intentionally.
As mentioned in the first paragraph, this deceptive page claims that some video cannot be played without the right video codec. It says that visitors can install that codec by downloading and executing some file. Although, it is very likely that this page is used to trick users into installing adware-type app, some browser hijacker, or some other unwanted, or even malicious application. Adware-type apps serve coupons, surveys, banners, pop-ups and/or other types of advertisement. Quite often those ads, if clicked, open questionable websites, or even cause download and/or installation of unwanted software by executing certain scripts. Browser hijackers change certain browser settings to an address of a fake search engine. What most adware-type apps and browser hijackers have in common is that they collect browsing data, for example, IP addresses, geolocations, entered search queries, addresses of visited websites and/or other information related to user's browsing habits. However, in some cases they are capable of gathering sensitive details as well.

A couple of examples of other pages that are more or less similar to this one are "Killer's IP Address", "Google Chrome Blocked For Security Reasons" and "Windows Error Code: WIN.DLL0151930". It is worthwhile to mention that such pages can be used users to trick into paying money for unnecessary software, services, or even giving scammers a remote access to their computers. In one way or another, such websites have to be ignored. If they get opened by a browser often, then it is likely that a browser has some PUA installed on it.
How did potentially unwanted applications install on my computer?
In some cases unwanted downloads and/or installations can be caused by clicking deceptive advertisements that are designed to execute certain scripts. However, more often users download and/or install PUAs when such apps are included in download and/or installation setups of other programs. This distribution method for potentially unwanted apps is called "bundling". Typically, users can decline offers to download and/or install PUAs via "Advanced", "Custom", "Manual" or other settings (or by unticking certain checkboxes) that are available in setups. When users do not do that when they download and/or install programs, then they allow for integrated PUAs to be downloaded and/or installed too.
How to avoid installation of potentially unwanted applications?
Downloads, installations should not be completed without checking setups for settings like "Custom", "Advanced" (or checkboxes) and declining offers to download and/or install additionally included, unwanted applications. Software (and files) should be downloaded only from trustworthy, official websites and through direct links. Third party downloaders (and installers), Peer-to-Peer networks (e.g., torrent clients, eMule), unofficial websites, etc., should not be used. Advertisements that appear on questionable pages should not be clicked as well - those ads tend to be be designed to open untrustworthy websites or even download, install unwanted apps. Also, there should not be any unwanted, unknown apps (extensions, add-ons or plug-ins) installed on a web browser and software of this kind installed on 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.
