The “Please Install New Codec Performer” is a misleading message that tries to persuade users that they need to install additional software to watch a video. When a user installs the required update, then more pop-up ads are displayed on the victim’s computer screen and the computer speed is slowed down due to the malicious program running on the background.
Codec Performer update is a potentially unwanted program that may install additional plugins (toolbars, extensions or add-ons) inside the Web browser in order to present unwanted advertisements to the computer's user. Malware programs like this, may contain malware (malicious software) in their code in order to compromise the computer's security and make it vulnerable to hackers or malicious Internet attacks.
Technically, “Codec Performer” is not a virus and is categorized as a malware program (“Potentially Unwanted Program (PUP)”) that may contain and install malicious programs on your computer, like adware, toolbars or viruses.
“Codec Performer” malicious software was probably installed without the user's knowledge because it is commonly bundled inside other freeware software which are downloaded -and installed- from known internet sites like “download.com (CNET)”, “Softonic.com”, etc. For that reason, you must always pay attention to the installation options for any program you install on your computer, because most software installers contain additional software that you never wanted to install. In simple words, DO NOT INSTALL ANY IRRELEVANT SOFTWARE that comes with the software installer of the program that you want to install. More specifically, when you install a program on your computer:
- DO NOT PRESS the “Next” button too fast at the installation screens.
- READ VERY CAREFULLY the Terms and Agreements before clicking “Accept”.
- ALWAYS SELECT: “Custom” installation.
- DECLINE to install any offered additional software that you don’t want to install.
- UNCHECK any option that says that your homepage and search settings will be modified.
