“Unknown Security Breach” Pop-Up
from Windows

Chrome regularly redirects me to the site, which says “Internet Service Provider: unknown Security Breach.” The pop-up indicates the error code 0xa297sa, HARDDISK_ROOTKIT_TROJAN_HIJACK.EXE Hard Disk Failure, and many other technical information that I do not understand. I can’t and actually fear of closing the browser. Need your help!

If your web browser got stuck with the “Internet Service Provider: unknown Security Breach” pop-up all of a sudden, it can only mean two things – you have either downloaded adware on the system or landed on a compromised website. Anyway, a quick solution would be to close your web browser forcefully using Task Manager and then scan the system with a professional anti-malware utility.

What the “Unknown Security Breach” pop-up actually is?

The “Unknown Security Breach” is a Tech-Support-Scam alert. It has been invented by scammers and disseminated through compromised websites or software bundles. In most of the cases, the pop-up starts emerging when the PC owner installs a bundled freeware from a doubtful download source without knowing that. When the “Unknown Security Breach” adware settles down on a default web browser, it starts generating the following message in a regular basis:

Inexperienced PC users who have never fall victims to tech support scam may easily get intimidated by the “Unknown Security Breach.” As you can see, the alert contains a long list of technical information about BSOD, dll errors, various error codes, etc. and warn about possible data leakage and system crash. To strengthen the feeling of urgency, scammers programmed the “Unknown Security Breach” pop-up to freeze the browser and the tactics seems to be working because many people have already fallen to call for the supposed Microsoft Support team.

Dialing the given number is a big mistake because the scammers on the other side of the handset may trick you into purchasing useless products or services. Even worse, you may be tricked into revealing information allowing criminals to access your PC remotely. In a nutshell, “Unknown Security Breach” virus is a nasty piece of infection, which has to be removed immediately.

Removing “Unknown Security Breach” pop-up

1. First of all, close the “Unknown Security Breach” scam alert by forcefully closing the entire web browser. For this purpose, press Ctrl + Shift + ESC and find the process of your web browser, click it, and select End Task.
2. Right after that, run a scan with a professional anti-malware utility, such as [d1].
3. OR uninstall potentially unwanted program that triggers the scam manually. Open Control Panel -> Programs and Features.
4. Fing unknown or suspicious applications and uninstall them one-by-one. To do so, click on the app and select Uninstall.
5. Finally, reset your web browser's default settings.
