How to get rid of virus notice? d155420ko90s739jn0vg.xso-adguard.co.in

Hello Richard,

That pop-up is not from Microsoft—it’s a common tech-support scam designed to scare you into clicking a malicious link. Here’s how to get rid of it and make sure nothing harmful remains:

1. Close the bad tab/window

Press Ctrl + Shift + Esc to open Task Manager.

Select Microsoft Edge (or the browser that’s showing the alert) and choose End task. > This kills the pop-up immediately.

2. Remove any leftover permissions

1. Open Edge and go to ⋯ > Settings > Cookies and site permissions > Notifications.
2. Delete any unfamiliar entries - especially one that looks like …xso-adguard.co.in.

Still in Settings, clear Cookies and cached files to flush any junk the site left behind.

3. (Optional) reset the browser & check extensions

Edge > Reset settings > Restore settings to their default values. Disable or remove any extension you don’t recognize.

4. Run a full security scan

• Start > Windows Security > Virus & threat protection > Scan options > Full scan.

When that finishes, run the Microsoft Defender Offline scan as well (same menu).

5. About windows-kb890830-x64-v5.134.exe

That file is Microsoft’s Malicious Software Removal Tool (MSRT), published through Windows Update each month. It’s legitimate and safe to run; it simply checks for widespread malware families. It isn’t related to the pop-up but can serve as an extra check.

How to avoid similar scams

Keep Windows and Edge up to date (Windows Update handles this automatically).

Leave Edge’s built-in pop-up blocker and SmartScreen filter enabled.

Never trust alerts that come from non-Microsoft web addresses, insist you “call right now” or pay in gift cards/crypto, or download software from an unfamiliar site.

If you follow the steps above, the rogue notice will disappear and your PC should be clean. Let me know if anything looks odd after the scans or if you have any other questions.

Stay safe,

Finn Dang
