CM Security Ads (Removal Instructions)

This page contains instructions to remove CM Security adware from your PC and stop CM Security ads in Chrome, Firefox, Internet Explorer, and Safari.

CM Security ads are caused by adware that injects the websites you visit with pop-up and in-text advertisements. Advertisements displayed by this adware usually say “Ads by CM Security” or “CM Security Ads” on them. In addition, the advertisements can be served across multiple web browsers installed on the infected computer system, including Chrome, Firefox, Internet Explorer, and Safari.

CM Security ads

If you find CM Security installed on your computer and notice CM Security ads in your browser you may wonder: what is CM Security? Is CM Security a virus? The answer is no. CM Security is not a computer virus but it does pose a threat and can be the initial sign of a malware infestation on your computer.

CM Security Distribution Method

Like most adware infections, CM Security adware primarily bundles with other programs that are downloaded by the user with out without consent. The most common way this happens is by downloading a program or file from a questionable distributor. Downloading items online such as freeware and torrent files will result in potentially unwanted programs infecting the user’s system. Even if a program is well known and trustworthy, downloading it from a malicious site will lead to infection.

If the computer user has recently downloaded a malicious program, CM Security adware might have automatically downloaded in the background without permission or knowledge of the user. The user might also be tricked into accepting the download under the guise of a program update. Malicious authors often hide the download behind a terms and conditions page, effectively tricking users into downloading adware. In some instances CM Security may be advertised as an extension to improve the user’s browsing experience in order to encourage a direct download. Regardless of how the system was infected, removal remains relatively unchanged.
