"A virus has been detected on your computer" removal instructions
What is "A virus has been detected on your computer"?
This is a typical tech support in which scammers claim to offer a legitimate technical support service. Typically, scammers behind such scams attempt to trick unsuspecting users into paying money for supposedly legitimate software or services, or even installing some Remote Administration Tool that would allow them to remotely access and control a computer. Either way, it is strongly recommended to ignore/not to trust such scams.
The main purpose of this technical support scam is to trick users into believing that a computer is infected with a virus and calling the +1 (603) 652-1871 number. It claims that a detected virus may compromise data such as passwords, browsing history, files stored on a computer and other confidential information. To prevent any of the possible damage users supposed to call the provided number within 5 minutes. This scam website is designed to look like an official Microsoft page, although, none of the actual, official Microsoft websites has anything to do with this site. Typically, scammers behind such scams attempt to deceive users into paying for the supposed "support" services or some software, and/or into giving them a remote access to a computer. By having such access they may be capable of stealing sensitive information such as credit card details, passwords, installing some malware (like ransomware, Trojans), accessing personal files, etc. Scammers may misuse accessed information, data to steal identities, personal accounts, make fraudulent purchases, transactions, and so on. In one way or another, such scams must be ignored. It is worthwhile to mention that users do not open such scam pages intentionally. In most cases they get opened through other shady websites, clicked deceptive ads or by installed potentially unwanted applications (PUAs).
Quite often installed PUAs are designed not only to open untrustworthy pages but also to collect various data related to user's browsing habits. For instance, IP addresses, entered search queries, addresses of visited pages, geolocations. In some cases they can be targeting sensitive, personal details as well. Moreover, PUAs can be designed to serve intrusive ads (like coupons, banners, surveys, pop-ups, etc.) as well. Usually those ads open various untrustworthy pages or even run scripts designed to cause download and/or installation of some unwanted software.

More examples of similar scams are "ERROR CODE 72", "Your Windows Is infected With (3) Viruses!" and "VIRUS ALERT FROM Windows". Typically, such scam pages are disguised as official Microsoft websites claiming that they have detected some virus, error, etc., and encouraging users to call the provided number as soon as possible. As mentioned in the second paragraph, users do not visit such pages intentionally. If a browser opens unreliable, deceptive pages by itself often, then it is very likely that it has some PUA installed on it.
How did potentially unwanted applications install on my computer?
It is common that various potentially unwanted applications are distributed by using download and installation setups of other programs. This distribution method is known as "bundling". Developers include PUAs in setups as additional offers and hope that users will not decline them. Typically, such offers are mentioned and can be declined in "Custom", "Advanced", and other similar settings of a setups. Although, users often download and/or install programs without checking and changing those settings. When they leave them unchanged, they download and/or install additionally included software together with a desired one. In some cases such downloads and/or installations can be caused by clicking deceptive advertisements that are designed to execute certain scripts.
How to avoid installation of potentially unwanted applications?
Third party downloaders, installers, Peer-to-Peer networks (like torrent clients, eMule, etc.), unofficial sites, freeware download pages, etc., can be used as tools to distribute various PUAs or even malicious apps. Therefore, software and files should be downloaded only from official websites and through direct links. Also, downloads and installations should not be finished without checking setups for "Advanced", "Custom" or other settings. It is common that such settings mention offers to download and/or install additionally included, unwanted apps. Advertisements that appear on various questionable, untrustworthy websites often either open untrustworthy websites or cause unwanted downloads, installations. Such ads should not be clicked as well. If there are any unwanted, suspicious extensions, add-ons, plug-ins installed on a browser, then they should be removed from it. Software of this kind that is installed on the operating system should be uninstalled too. If your computer is already infected with PUAs, we recommend running a scan with Malwarebytes for Windows to automatically eliminate them.
