Trojan Virus on Microsoft Edge

Well done for being suspicious, you would be amazed how many users fall for this!

Your PC is not infected with malware, this is a well known Tech Support Scam do not click anything on that page and do not phone any number on that page.

When this happens, open Task Manager (Ctrl + Shift + Esc)

On the processes tab, locate your browser and end task on that

You can then continue to user your PC and browse the Internet

This is caused by a browser re-direct on a page you are visiting, try to avoid any page that jumps out to this sort of page.

This behavior matches a common tech support scam and scareware pop‑up in Microsoft Edge, not a confirmed trojan infection.

What happened

• Scam pages can open from otherwise legitimate sites via malicious ads.
• They show full‑screen warnings, loud alarms, fake “Microsoft Defender” or “Windows security” messages, and unverified phone numbers to call.
• These pages only run in the browser; they do not mean the PC is blocked or that a trojan is installed, especially if security scans show clean results.

Why the PC is likely safe

• The pop‑up was closed using End Task in Task Manager, which is the correct way to exit a frozen or hijacked Edge window.
• After restart, both Clean Sweep and Avast reported no malware.
• Similar cases documented for Edge show that if no software was installed and no remote access or instructions from the scammers were followed, the device is not hacked and no further action is usually required.

How to close these pop‑ups safely If this happens again:

1. Try exiting full screen with F11, then close the tab.
2. If that fails, press Ctrl+Shift+Esc, open Task Manager, select Microsoft Edge, and choose End task.
3. As a last resort, hold the power button to turn the PC off, then restart.

What to do now in Edge

1. Clear Edge’s cache and data to remove any remnants of the scam page:
   • Open Edge, go to settings to clear browsing data (cache, cookies, history).
2. Ensure pop‑up blocking and protections are on:
   • Edge includes a pop‑up blocker and Microsoft Defender SmartScreen to help block malicious or scam sites.
3. Consider enabling or keeping on features like scareware blocker in Edge, which uses on‑device AI to detect and block deceptive full‑screen scam pages before they trap the browser.

Extra protection steps

• Keep Windows and Microsoft Defender (or the chosen antivirus) up to date.
• Avoid calling any phone numbers shown in browser pop‑ups or granting remote access to anyone who contacts claiming to be “Microsoft support.”
• If the same malware warning keeps reappearing and a real infection is suspected, run a Microsoft Defender Offline scan from Windows Security to detect hidden threats.

If no software was installed from that page, no phone number was called, and security scans remain clean, the incident can be treated as a browser‑based scam rather than an actual trojan infection.
