This page aims to help you remove Call Microsoft Customer Support Scam. Our removal instructions work for Chrome, Firefox and Internet Explorer, as well as every version of Windows.

Call Microsoft Customer Support Scam is a browser-redirecting software that is programmed to generate ads, cause page redirects, track the user’s online activities and impose modifications to their browser program. Researchers claim that this program behaves as a browser hijacker because the moment it appears on the user’s computer it could try to install a new search engine, change the default homepage and/or new-tab page as well as initiate the generation of various sponsored commercials and web pages. Judging by the way it may affect the browser’s settings, it appears that Call Microsoft Customer Support really belongs to this category of software, and it may affect any browser – be it Chrome, Firefox, Internet Explorer, Opera or some other browsing program.

However, before you get concerned about your computers’ safety, we want to emphasize that Call Microsoft Customer Support is a legitimate program. It has nothing in common with threats such as Ransomware, Trojan horses or other computer viruses and typically does not attempt to cause harm to the PC where it’s installed. The problem with this browser hijacker is that its developers use it to generate advertising content on the users’ screens by hijacking their browsers. The primary goal of the software is to generate as many pay-per-click ads as possible and make you click on them because this brings revenue to its creators. You, however, can quickly uninstall Call Microsoft Customer Support and remove its imposed browser changes if they cause you disturbance. In the next lines, we will tell you more about how to do that, so stay with us and pay attention to the information that follows.

Call Microsoft Customer Support Scam may cause problems with browsing. Here is what you need to know about this program:

Typically, Call Microsoft Customer Support ads may appear on your screen after the installation of a program bundle. It is very common for the browser hijackers to get distributed as suggested optional components in setup packages with other programs. That way, the users typically install them along with the main program, without knowing about their presence in the package. Once in the system, the hijacker may modify some Windows Registry Keys and change the settings of all browsers that are installed on the affected computer, including Chrome, Firefox, IE or any other. These modifications usually do not require your direct approval. Replacement of the default homepage or the search engine are some of the first visible symptoms.

Usually, Call Microsoft Customer Support installs also some ad-generating scripts to display third-party advertising content on the web page you are visiting. These ads may prompt you to download security programs, get discount vouchers, and more. However, most of them may not be as trusted as they look and some may even be fake. Either way, clicking on these ads is not recommended. You may suddenly get redirected to other web locations, which have nothing to do with what was getting promoted in the ads you clicked on, and you may even land on compromised websites. While such browser redirects are more of an annoyance than an actual, some of the ads and pop-ups may redirect you to phishing sites, which can infect your computer with malware such as Trojans, Ransomware, and other cyber threats. For this reason, we advise you to remove Call Microsoft Customer Support as soon as you notice that something’s been changed about your browser. It is not difficult to recognize the changes and the potential ads that the hijacker might display inside your browsing program.

The fastest way to uninstall this hijacker is to scan the system with a malware removal program like the professional Call Microsoft Customer Support removal tool from the current page. It will automatically check all the installed programs and browser extensions and help you eliminate the unwanted ones without risk for your system. Once you’ve deleted all suspicious data, it’s a good idea to reset your web browser settings as well. You can also remove the potentially unwanted program by following the guidelines we have prepared below.

Common methods used to distribute ad-supported applications

Many potentially unwanted applications and ad-generating programs may get installed on a computer when the users download and install free programs without paying attention to the setup details. To avoid annoyances such as the hijacker we are currently focusing on, make sure to avoid using the “Fast” or the “Recommended” setup settings when installing new software. The problem with them is those options usually do not reveal information about any third-party applications that may have been bundled with the main program. According to security specialists, the fast installation method is popular among most of the computer users. To avoid the installation of unwanted applications, however, you should use the “Advanced” or the “User” setup options and see if there’s anything added that looks undesirable (or simple unneeded). Once you see checkboxes with pre-marked download components, uncheck them if you think the optional installs should not be allowed inside your PC.
