“Your system is heavily damaged by (4) virus!” – fake alert used to spread malware

The main page of "Your system is heavily damaged by (4) virus!" scamPlease don't believe this fake alert as there is nothing wrong with your device

“Your system is heavily damaged by (4) virus!” is a social engineering attack know as bait or tech support scam[1]. Its developers use multiple psychological strategies to create the feeling of immediacy, the risk of a fatal system crash, and fear of personal data loss.

To protect the system from possible consequences, the victim is asked to purchase the PC Smart Cleanup utility, which is nothing else but malware. In the middle of March 2018, a new version of this dangerous infection has been spotted circulating around. Dubbed as Four Virus, this potentially malicious infection is considered to become as widespread as the Android and iPhone viruses.

According to people's reports, a target for both Four virus and “Your system is heavily damaged by (4) virus!” versions are iPhone, Android, and iPad users. The tablet and smartphone users may get another variant, stating that your battery is badly damaged by 4 virus.

name Your system is heavily damaged by (4) virus!
Type Adware, PUP, tech support scam
Purpose Convince people to download a rogue tool that shows fake scan results trying to persuade you into purchasing its worthless paid version
Risks PUP installation, malware infections, financial losses, privacy issues
Distribution Software bundles, fake Flash Player updates, file-sharing platforms, deceptive ads
Removal Scan your device with the FortectIntego system tool to remove adware and tracking cookies

Nonetheless, comparing this scam with other samples of the online felony, it does not manifest any extraordinary behavior or features. On the other hand, there is a distinguishable feature. Unlike the majority of tech support scams which alert users with Zeus virus, for instance, Your computer has been infected with Zeus virus and threatens that your Facebook login and email account information is about to be stolen, this sample of the tech support scam behaves a bit differently.

It says that your computer is heavily damaged by four virus. However, it is unknown whether the “four” indicates the malware's name or the number of viruses supposedly detected on the system. Furthermore, this tech support scam sample advised you to acquire technical support not by dialing a specific number but by installing a program called PCSmartCleanup. Here's where the problem lies.

The Four virus is not only intrusive as it locks the web browser completely but can expose the system to potentially unwanted programs (PUPs). The pretend-to-be legitimate PCSmartCleanup utility has been condemned for questionable behavior, such as the usage of cookies, delivery of predetermined scan results, and ongoing proposals to purchase the Advanced or Licensed version. Thus, it is not recommended to install it or if you already did, remove it. Speaking of the scam, ignore it and close the tab.

If you got redirected to its counterpart — “Your Computer is heavily damaged! (33.2%)” scam – you should not comply with the demands either. If you cannot exit the page, shut it down via the Task Manager. In addition, it is recommended to scan the device and remove “Your system is heavily damaged by (4) virus!” web elements. You can do so with the assistance of FortectIntego.

You are most likely to get redirected to the article's culprit scam site after you click on the play button in an illegal movie streaming or gaming site, click on deceptive as, etc. Speaking of PC-based tech support scams, you might encounter it if you install a corrupted application or browser extension[2].

Therefore, it is of utmost importance to pay attention to the installation of any new software, especially if you downloaded it from a third-party vendor. Always choose the Advanced/Custom installation modes over the Recommended/Standard/Quick ones. Only then will you be able to deselect all additional, untrustworthy, questionable applications from installing on your device.

How to prevent from getting adware

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.

If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.


Recover files after data-affecting malware attacks

While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.

Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
