Your Computer May Have a Virus! Scam

Also Known As: "Your Computer May Have a Virus!" virus
Type: Adware
Damage level: Medium

What is Your Computer May Have A Virus!?

"Your Computer May Have A Virus!" is a fake error message displayed by a malicious website that users often visit inadvertently - they are redirected by various potentially unwanted programs (PUPs).

These programs infiltrate systems without consent or commonly trick users to install by falsely claiming to provide various "useful features". As well as causing redirects, PUPs track Internet browsing activity and generate intrusive online advertisements.

Your Computer May Have A Virus! adware

The error message states that the system is infected, and private information (credit card details, logins/passwords, webcam access, etc.) is at risk. It suggests that the malware must be eliminated immediately, however, unlike other similar errors, "Your Computer May Have A Virus!" does not encourage users to contact technical support.

Rather, it proposes installation of a malware removal tool. As mentioned above, however, "Your Computer May Have A Virus!" is fake. Criminals attempt to trick users into installing PUPs by promoting them as malware removal tools. Therefore, ignore this error message. You can remove it simply by closing the web browser.

Be aware also that PUPs continually track browsing activity by gathering various user-system information (for example, geo-locations, Internet Protocol addresses, website URLs visited, pages viewed, queries entered into search engines, mouse/keyboard activity, etc.) that might contain personal details.

PUP developers aim to generate as much revenue as possible by selling the collected data to third parties (potentially, cyber criminals) who also generate revenue by misuing personal details. This can lead to serious privacy issues or even identity theft.

Another downside is display of intrusive advertisements. PUPs deliver coupon, banner, pop-up, and other similar ads that often conceal underlying content, thereby significantly diminishing the browsing experience. Furthermore, they can redirect to malicious websites or even activate scripts that download and install additional malware/PUPs.

Therefore, even accidental clicks might result in high-risk adware or malware infections. We strongly advise you to uninstall all PUPs immediately.

There are dozens of fake errors similar to "Your Computer May Have A Virus!" including, for example, Unauthorized Access Detected !, Unknown System Failure!, and Google Chrome Warning Alert. All state that the system is infected, missing files, or damaged in other similar ways.

These claims are merely attempts to trick users into calling and paying for unnecessary technical support, or downloading fake malware removers. All PUPs are virtually identical.

By offering various 'useful features', PUPs attempt to give the impression of legitimacy, however, they are useless for regular users, merely cause unwanted redirects (thereby promoting various dubious websites), collect various user-system information (which is later sold to third parties), and deliver intrusive advertisements (using the "Pay Per Click" advertising model).

Most of the promoted websites are fake search engines. As with PUPs, fake search engines also promote other websites (by generating fake results), deliver intrusive ads, and record various user-system information. Bear in mind that fake search results (and intrusive ads) can redirect to malicious websites. Therefore, using a fake search engine is very risky.

How did adware install on my computer?

As well as via intrusive ads, PUPs are distributed using a deceptive marketing method called "bundling" - stealth installation of third party applications with regular software/apps. Developers hide "bundled" programs within the "Custom" or "Advanced" settings of the download/installation processes.

Rushing these processes, skipping steps, and clicking various intrusive advertisements, exposes systems to risk of various infections and compromises users' privacy.

How to avoid installation of potentially unwanted applications?

The main reasons for computer infections are poor knowledge and careless behavior. Therefore, be very cautious browsing the Internet and downloading/installing software. Cyber criminals put a great deal of time and effort into designing intrusive online advertisements.

Therefore, determining if they originate from the visited (legitimate) website is virtually impossible. Do not take the risk of clicking intrusive ads. In addition, download your software from official sources only using (if possible) the direct download link. Third party downloaders commonly include ("bundle") additional apps.

We strongly advise against using these downloaders. It is also important to carefully analyze each download/installation step (especially the "Custom/Advanced" settings) and opt-out of all additionally-included programs.
