Removal guide for unwanted apps that open pages like Important Security Alert! scam
What is Important Security Alert! scam?
As a rule, technical support scams like this one are designed by scammers who seek to deceive visitors into contacting them via the provided number. Once contacted, scammers attempt to trick unsuspecting users into paying money for some unnecessary software, services. In some cases they ask for a remote access to the computer. In one way or another, such scam pages should never be trusted. It is worthwhile to mention that users do not visit websites of this type on purpose, it is common that they get opened by potentially unwanted applications (PUAs).
As written in this scam website, it has detected some virus which may cause problems like loss of passwords, browsing history, some sensitive information (like CC details) and files stored on the hard disk. It is designed to trick visitors into believing that they will not be able to access the operating system if they will ignore this warning/if they will not call the 0808-143-3686 number. In other words, scammers behind it attempt to trick visitors into thinking that they can solve the problem (remove virus) by using customer service representatives. It is strongly recommended not to call the provided number. This scam page is designed to look like some official Microsoft page, however, the actual Microsoft company (or its support team) has nothing to do with it. As mentioned in the introduction, scammers behind technical support scams try to trick visitors who contact them to pay money for unnecessary services or some software. In some cases they even ask users to give a remote access to their computers, e.g., install some Remote Administration Tool (RAT). By having a remote access to the computers scammers could install malware on them, steal personal, sensitive information, or use such access for other malicious purposes. It is worthwhile to mention that this particular page displays a pop-up asking users to enter their username and password as well. It is strongly recommended not to trust such pages and/or enter any personal information on them.
As mentioned in the introduction, users do not visit tech-support scam pages intentionally, it is common that such sites get opened by PUAs that are installed on browsers and/or computers. Such apps can be designed not only to open untrustworthy websites but also to collect browsing data and other information, and/or serve advertisements. More often than not PUAs gather data such as IP addresses, websites of visited pages, entered search queries, geolocations, and so on. Nevertheless, PUAs can be designed to record sensitive, confidential information as well. Moreover, their developers could sell recorded information to third parties (potentially cyber criminals) who would misuse it to generate revenue in other ways. Also, apps of this type can be (and often are) designed to serve coupons, banners, surveys, pop-ups and other forms of ads. Those ads usually lead to untrustworthy websites, however, they may be designed to cause downloads, installations of unwanted applications by executing certain scripts. PUAs can be the reason behind identity theft, problems with browsing safety, online privacy, and other issues. For these reasons any PUA that is installed on a browser and/or operating system should be removed from it as soon as possible.

"TROJAN Error Code 0xdc2dgewc", "Windows Defender - Security Warning" and "Microsoft Important Alert" are a couple of examples of other scam websites that are quite similar to this one. What most of them have in common is that they are designed to look like official Microsoft websites and used with a purpose to trick visitors into calling scammers via the provided number. If a browser opens such pages often, then it is very likely that it already has some PUA installed on it.
How did potentially unwanted applications install on my computer?
Usually various PUAs are distributed by integrating them in setups of other programs as additional offers. This distribution method is known as "bundling". In most cases offers to download and/or install additionally included apps are mentioned in settings of setups like "Advanced", "Custom", "Manual". However, not all users check (and change) those settings before they complete downloads and/or installations. In such cases they agree with offers to download and/or install included PUAs as well. Sometimes potentially unwanted apps can be downloaded and/or installed through deceptive advertisements that are designed to execute certain scripts. However, it can happen only if ads of this type are clicked.
How to avoid installation of potentially unwanted applications?
It is advised to always check what are "Custom", "Advanced", "Manual" and other settings (or checkboxes) of any download and/or installation setup and see if they mention offers to download and/or install additional, unwanted software. Software should not be downloaded from/through untrustworthy, unofficial websites, torrent clients, eMule (and other Peer-to-Peer networks), third party downloaders, installers via third party installers, etc. It should be done by using official pages and direct links. Advertisements that are displayed on questionable pages should not be clicked as well. It is common that such ads are designed to open potentially malicious pages or cause downloads, installations of unwanted programs. If some unwanted, suspicious extension, plug-in or add-on is already installed on a browser, then it should be removed. The same should be done with software of this kind that is installed on the operating system. If your computer is already infected with PUAs, we recommend running a scan with Malwarebytes for Windows to automatically eliminate them.
