“Your Windows OS is damaged” scam promotes fake updates

Your Windows OS is damaged virus

Your Windows OS is damaged is yet another scam[1] created for tricking Windows OS users that they need to install an update. However, this warning does not have anything in common with Microsoft, and you should not install any content from such website.

Redirects to Your Windows OS is damaged scam website typically starts after the installation of the adware program. This usually happens unintentionally when downloading free programs from the internet.

However, “Your Windows OS is damaged” redirect might occur when you visit a high-risk website too. Thus, if this website shows up in the browser only once, your device should not be infected unless you were tricked into clicking an “Update” button on the scam website.

Creators of “Your Windows OS is damaged” virus use social engineering[2] to make users believe that they simply do not have a choice but to install the supposed “update.” The fake alert looks like genuine Windows popup and has timer added to it. The message states:

“System Warning
Your Windows OS is damaged
Your Windows version:
Note: Your current version of Windows Security infected with Viruses and other malicious applications. Viruses must be removed in:

[timer]

Important: Please click UPDATE button to install the latest version and protect your data”

As evident, hackers try to shock the confused victim and make them click on the fake update. If the user proceeds, the additional dubious application is installed. However, if the user clicks on “Update” button, he or she will not be downloading an update for Windows, but rather a malicious application.

As we have mentioned earlier, “Your Windows OS is damaged” pop-ups are usually caused by an adware program installed on your computer. This potentially unwanted program (PUP) is not dangerous itself. However, it might make the system vulnerable to malware attacks and cause numerous problems when browsing the web, for example:

  • delivery of pop-ups, banners, in-text or other types of online ads;
  • delivery of fake security alerts;
  • promotion of questionable programs;
  • redirects to technical support scam websites;
  • redirects to promotional sites;
  • data tracking.

All these activities diminish browsing experience. However, chances to catch a computer virus or reveal personal information to cyber criminals increase as well. Thus, you should not hesitate and remove “Your Windows OS is damaged” adware from the system.
