Virus Scanner POP-UP Virus

Also Known As: "Virus Scanner" virus
Type: Adware
Damage level: Medium

What is Virus Scanner?

"Virus Scanner" is a fake warning message displayed by a deceptive website. This site's URL is typically used to promote spam email campaigns - messages state that users' email clients are infected and encourage them to immediately perform a scan and remove all issues.

In some cases, however, users are redirected to this website by various potentially unwanted programs (PUPs) that infiltrate systems without permission. As well as causing redirects, potentially unwanted programs deliver intrusive advertisements and gather various sensitive information.

Virus Scanner scam

The website states that users' emails are infected and encourages them to scan them. To achieve this, they must first sign-in. Be aware, however, that this is a scam. Cyber criminals collect personal information (emails addresses and passwords) by tricking gullible users into signing-in. Entered information is immediately saved on a remote server.

Furthermore, cyber criminals misuse collected information to generate revenue - they might steal victims' identities, perform online purchases, transfer money, and so on. Therefore, entering email information on the website that displays "Virus Scanner" message can lead to serious privacy issues and significant financial loss.

If you have already entered your personal data, you should immediately change passwords of your email and other accounts that are registered with the same email address (cyber criminals might have used your email address to restore accounts' passwords or to log into websites such as PayPal, Facebook, and so on).

You should also leave the "Virus Scanner" site immediately, however, note that some rogue sites employ scripts that prevent users from closing browsing tabs/windows. In these cases, terminate the browser using Task Manager or simply reboot the system. After re-running the browser, do not restore the previous session, otherwise the deceptive sites are also reopened.

As mentioned above, PUPs deliver various intrusive advertisements. To achieve this, developers employ tools that enable placement of third party graphical content on any site. Therefore, ads often conceal underlying website content, thereby significantly diminishing the browsing experience.

In addition, they can redirect to malicious sites and even execute scripts that stealthily download/install malware or other PUPs. Therefore, even a single accidental click might result in high-risk computer infections. Another important issue is information tracking.

Research shows that many PUPs record Internet Protocol (IP) addresses, website URLs visited, pages viewed, search queries, keystrokes, and other collected data that includes personal details.

The data is shared with third parties (potentially, cyber criminals) who generate revenue by misusing private information. Therefore, data tracking can lead to serious privacy issues or even identity theft. For these reasons, we strongly advise you to uninstall all potentially unwanted programs immediately.

The Internet is full of deceptive websites that display fake errors. For example, User Access Suspended, ERROR 268d3x8938, Your McAfee Subscription Has Expired, and many others. All claim that the system is damaged (e.g., infected, missing files, or similar), however, unlike "Virus Scanner", these errors do not ask to you log-in.

They encourage users to call fake 'tech support' (and pay for services that are not required) or install fake anti-virus/anti-spyware tools (and purchase 'full versions'). Potentially unwanted programs also share many similarities.

By offering a wide range of "useful features", they attempt to give the impression of legitimacy, they are designed only to generate revenue for the developers.

Rather than enabling the functions promised, these programs cause unwanted redirects, gather sensitive information, and deliver intrusive advertisements, thereby posing a direct threat to your privacy and Internet browsing safety.

How did potentially unwanted programs install on my computer?

Some PUPs have official download websites, however, most infiltrate systems without users’ permission, since developers proliferate them using intrusive advertisements and a deceptive marketing method called "bundling". Developers hide "bundled" applications within "Custom/Advanced" settings (or other sections) of the download/installation processes.

Furthermore, many users are very likely to rush these procedures and skip steps. In addition, they often click advertisements without understanding the possible consequences. This behavior often leads to inadvertent installation of PUPs - users expose their systems to risk of various infections and compromise their privacy.

How to avoid installation of potentially unwanted applications?

The main reasons for computer infections are poor knowledge and careless behavior. The key to safety is caution. Therefore, pay close attention during download/installation processes, and when browsing the Internet. You should select "Custom/Advanced" settings and closely analyze each window of the download/installation dialogs.

Opt-out of all additionally-included programs and decline offers to download/install them. Download software from official sources only, using direct download links. Third party downloaders/installers are used to proliferate PUPs (the "bundling" method), and thus, these tools should not be used.

Note that intrusive ads typically seem legitimate, since developers invest many resources into their design, however, they often lead to gambling, pornography, adult dating, and other dubious sites. If you encounter these ads, immediately remove all suspicious applications and browser plug-ins.

If your computer is already infected with PUPs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
