Your System Is Heavily Damaged By (4) Virus removal instructions
What is Your System Is Heavily Damaged By (4) Virus?
Displayed by various deceptive websites, "Your System Is Heavily Damaged By (4) Virus" is a fake error message. Research shows that users often visit these sites inadvertently - they are redirected by intrusive ads (displayed by other untrustworthy websites) or potentially unwanted programs (PUPs) that infiltrate systems without permission. As well as causing redirects, PUPs deliver intrusive advertisements, record user-system information, and (in some cases) run unwanted background processes.
The "Your System Is Heavily Damaged By (4) Virus" error states that the system is infected with a number of viruses and, for this reason, personal data might be corrupted. This message is followed by an encouragement to download a type of system clean-up tool. Be aware, however, that "Your System Is Heavily Damaged By (4) Virus" is fake. Essentially, criminals generate revenue by promoting various potentially unwanted programs. Furthermore, websites that display this error detect which device the visitor is using - the operating system (e.g., Windows, Apple iOS, Android, etc.) the device is running - and displays a different message accordingly. Despite this, you should ignore the "Your System Is Heavily Damaged By (4) Virus" message. Promoted applications are categorized as potentially unwanted programs and, thus, you must never agree to download them. You are strongly advised to immediately leave websites that display "Your System Is Heavily Damaged By (4) Virus". Note that some rogue sites employ scripts that prevent users from closing browsing tabs/windows. In these cases, close the browser via Task Manager or simply reboot the system, however, it is very important NOT to restore previous session after re-running the browser, otherwise the malicious sites are re-opened.
As mentioned above, potentially unwanted programs deliver intrusive advertisements. To achieve this, developers employ various tools (such as "virtual layers") that enable placement of third party graphical content on any site. Therefore, displayed ads often conceal underlying website content, thereby diminishing the browsing experience. More importantly, intrusive ads can lead to malicious sites and run scripts designed to download/install malware. Therefore, even a single click can result in high-risk computer infections. Another significant downside is information tracking. PUPs are known to collect various user-system information relating to Internet browsing activity. Collected data (IP addresses, keystrokes, URLs visited, pages viewed, search queries, etc.) typically includes personal details that developers share with third parties. There is a high probability that these people will attempt to misuse private information to generate revenue. In doing so, these third parties can cause serious privacy issues or even identity theft. Some PUPs misuse resources to mine cryptocurrencies or run other unwanted processes in the background. These applications significantly diminish overall system performance. All potentially unwanted programs must be eliminated immediately.
"Your System Is Heavily Damaged By (4) Virus" shares many similarities with VIRUS ALERT FROM MICROSOFT, Windows Warning Alert, Code 055BCCAC9FEC, and dozens of other fake error messages. All claim that the system is damaged (e.g., infected, missing files, etc.), however, these claims are merely attempts to trick users into downloading fake anti-virus programs or calling and paying for technical support that is not required. Potentially unwanted programs are all very similar. By offering "useful features", PUPs attempt to give the impression of legitimacy, however, they are designed only to generate revenue for the developers. Potentially unwanted programs deliver no real value for regular users and pose a direct threat to your privacy and Internet browsing safety.
How did potentially unwanted programs install on my computer?
To proliferate PUPs, developers employ intrusive advertisements and a deceptive marketing method called "bundling" (stealth installation of third party applications together with regular software/apps). Developers do not properly disclose installation of "bundled" programs - they conceal them within "Advanced/Custom" settings or other sections of the download/installation processes. In addition, many users rush these procedures and skip steps. In addition, they often click various dubious links/ads. This careless behavior often leads to inadvertent installation of potentially unwanted programs.
How to avoid installation of potentially unwanted applications?
The main reasons for computer infections are poor knowledge and lack of caution. Therefore, pay close attention when browsing the Internet and, especially when downloading/installing software. Cyber criminals put a great deal of effort into intrusive ad design, thereby making them appear legitimate. Despite this, they redirect to gambling, adult dating, pornography, and other dubious sites. Therefore, if you encounter these ads, immediately remove all suspicious applications/browser plug-ins. It is also recommended that you select "Custom/Advanced" options and carefully analyze each window of the download/installation dialogs. In addition, decline offers to download/install additional applications and opt-out of those already included. Note that criminals monetize third party downloaders/installers using the "bundling" method. Therefore, software should be downloaded from official sources only using direct download links.
