Issue: How to Remove “Windows Has Detected a Malicious Virus On Your System” Pop-Up?

Hello all. Today I get a really suspicious warning claiming “Windows Has Detected a Malicious Virus On Your System.” It does not look like a genuine alert from Microsoft. The following is the telephone number that I’m supposed to call to remove the virus: 877-384-3078. Have you heard something about that?

Solved Answer

Scammers are actively improving their strategies to lure people into scam affairs and shake down their money. While prize giveaway, online surveys, and similar scam types[1] are still alive, tech support scam is currently the most popular technique used by cyber villains.

While most of Tech-Support-Scams are really catchy, the others look rather fishy and unprofessional. “Windows Has Detected a Malicious Virus On Your System” Tech-Support-Scam would probably fall for the scam gimcracks.
The “Windows Has Detected a Malicious Virus On Your System” scam is caused by adware infection or websites infected with a malicious code. It shows up as a pop-up window on a user’s default web browser and usually freezes it up. The pop-up contains the following information:

Although the Windows Has Detected a Malicious Virus On Your System scam exhibits all Tech-Support-Scam traits, it looks neither trustworthy, nor professional. Although it’s stated that “Windows” has detected a virus and that the provided number belongs to “Certified Windows Technicians,” the pop-up does not contain any Microsoft’s trademarks or specific information, for example, what virus was detected.Remove “Windows Has Detected a Malicious Virus On Your System” scam
