Attention Your Computer Has Been Infected POP-UP Scam

Also Known As: "Attention Your computer has been infected" virus
Damage level: Medium

What is Attention Your Computer Has Been Infected?

Similar to Your Computer Might Be Infected By Trojans, Computer Detected To Be Corrupted, Spyware Detected On Your Computer!, and many others, "Attention Your Computer Has Been Infected" is a fake error message displayed by deceptive websites.

In most cases, users visit these sites inadvertently - they are redirected by intrusive advertisements (delivered by other rogue sites) or potentially unwanted programs (PUPs) that infiltrate systems without permission. As well as causing redirects, potentially unwanted programs deliver intrusive advertisements and record user-system information.

Attention Your Computer Has Been Infected scam

The error message essentially states that system is infected and personal data (banking information, logins/passwords, history, files, etc.) is at risk. The malware must be eliminated immediately and users are encouraged to call fake 'tech support' via a telephone number ["1-(855) 399-1933"] provided. Users are then supposedly guided through the malware removal process.

This is a scam - the "Attention Your Computer Has Been Infected" error is fake. Cyber criminals attempt to scare and trick unsuspecting users into calling and paying for tech support that is not required - your computer is probably optimized and virus-free. Ignore "Attention Your Computer Has Been Infected" and never attempt to call the aforementioned telephone number.

This error can be removed simply by closing the web browser. Some rogue sites employ scripts that prevent users from closing browsing tabs/windows. In these cases, terminate the browser via Task Manager or restart the system. Do not restore the previous session, otherwise the next time you open the browser, you will return to the malicious site/s.

Potentially unwanted programs deliver various intrusive advertisements, such as coupons, banners, pop-ups, and so on. These are delivered using various tools (e.g., "virtual layers") that enable placement of third party graphical content on any site. Therefore, intrusive ads often conceal underlying content, significantly diminishing the web browsing experience.

These ads can redirect to infectious websites or execute scripts that stealthily download/install malware. Therefore, even a single click might result in high-risk computer infections. Potentially unwanted programs are also notorious for data tracking. Research shows that many PUPs record information that includes personal details.

IP addresses, website URLs visited, pages viewed, search queries, and other collected data is later shared with third parties (potentially, cyber criminals). These people misuse private information to generate revenue. Therefore, the presence of data-tracking apps can lead to serious privacy issues or even identity theft. You are advised to uninstall all PUPs immediately.

As mentioned above, "Attention Your Computer Has Been Infected" shares many similarities with dozens of other fake errors. All claim that system is damaged , however, these claims are merely attempts to extort money from gullible users. PUPs are also known to share many similarities.

By offering "useful features", they attempt to give the impression of legitimacy. Bear in mind, however, that these programs are designed only to generate revenue for the developers.

Rather than giving any real value for regular users, they cause unwanted redirects, gather sensitive information, and deliver intrusive ads, thereby posing a direct threat to your privacy and Internet browsing safety.

How did potentially unwanted programs install on my computer?

Some PUPs are known to have official download/installation websites, however, due to the lack of knowledge and careless behavior of many users, these programs typically infiltrate systems without consent. Be aware that developers promote PUPs using intrusive advertising and "bundling" methods.

"Bundling" is essentially stealth installation of PUPs together with regular software. Developers hide "bundled" PUPs within various sections (usually "Custom/Advanced" settings) of the download/installation processes.

Furthermore, many users are likely to click advertisements and skip download/installation steps. In doing so, they expose their systems to risk of various infections and compromise their privacy.

How to avoid installation of potentially unwanted applications?

To prevent this situation, be very cautious when browsing the Internet and downloading/installing software. Developers invest many resources into intrusive ad design, thereby making them seem legitimate. When clicked, however, most lead to dubious websites (gambling, adult dating, pornography, and similar).

If you continually encounter these ads, check the list of installed apps/browser plug-ins and remove any suspicious entries. In addition, carefully analyze each window of the download/installation dialogs and opt-out of all additionally-included programs. Programs must be downloaded from official sources only, using direct download links.

Third party downloaders/installers often include rogue apps (developers monetize them via "bundling" method). Therefore, do not use these tools. The key to computer safety is caution. If your computer is already infected with PUPs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.

How to identify a pop-up scam?

Pop-up windows with various fake messages are a common type of lures cybercriminals use. They collect sensitive personal data, trick Internet users into calling fake tech support numbers, subscribe to useless online services, invest in shady cryptocurrency schemes, etc.

While in the majority of cases these pop-ups don't infect users' devices with malware, they can cause direct monetary loss or could result in identity theft.

Cybercriminals strive to create their rogue pop-up windows to look trustworthy, however, scams typically have the following characteristics:

  • Spelling mistakes and non-professional images - Closely inspect the information displayed in a pop-up. Spelling mistakes and unprofessional images could be a sign of a scam.
  • Sense of urgency - Countdown timer with a couple of minutes on it, asking you to enter your personal information or subscribe to some online service.
  • Statements that you won something - If you haven't participated in a lottery, online competition, etc., and you see a pop-up window stating that you won.
  • Computer or mobile device scan - A pop-up window that scans your device and informs of detected issues - is undoubtedly a scam; webpages cannot perform such actions.
  • Exclusivity - Pop-up windows stating that only you are given secret access to a financial scheme that can quickly make you rich.

How do pop-up scams work?

Users land on their online lures after clicking on fake download buttons, using a torrent website, or simply clicking on an Internet search engine result.

Based on users' location and device information, they are presented with a scam pop-up. Lures presented in such pop-ups range from get-rich-quick schemes to fake virus scans.
