Step 1: Do NOT Click Anything on the Pop-Up
The first rule when dealing with virus warning pop-ups:
❌ Do Not:
- Click “OK”, “Cancel”, or “Scan Now”
- Call any number shown
- Download suggested software
Even clicking “X” can sometimes trigger malicious scripts.
Step 2: Force Close Your Browser Safely
If your browser is stuck or fullscreen:
How to Force Close Browser
- Press Ctrl + Shift + Esc
- Open Task Manager
- Select your browser (Chrome / Edge / Firefox)
- Click End Task
This safely shuts down the pop-up without interacting with it.
Step 3: Reopen Browser in Safe Mode (Without Restoring Tabs)
When reopening your browser:
- Choose “No” if asked to restore previous tabs
- This prevents the pop-up page from reopening
If the pop-up keeps coming back, continue with the next steps.
Step 4: Remove Suspicious Browser Extensions
Browser extensions are a major cause of repeated virus warnings.
How to Remove Malicious Extensions
- Open browser settings
- Go to Extensions
- Remove:
- Unknown extensions
- Extensions you didn’t install
- Anything related to ads, coupons, or “security alerts”
Restart your browser after removal.
Step 5: Turn Off Spam Browser Notifications
Many fake virus alerts come through browser notifications.
Disable Notifications (Chrome / Edge)
- Go to Settings
- Open Privacy & Security
- Click Site Settings
- Open Notifications
- Remove suspicious websites from “Allowed”
This step alone fixes the issue for many users.
Step 6: Run a Full Virus Scan Using Windows Security
Now let’s check if your PC actually has malware.
How to Scan with Windows Defender
- Open Windows Security
- Click Virus & Threat Protection
- Select Scan Options
- Choose Full Scan
- Click Scan Now
Windows Defender is powerful and enough for most users.
Step 7: Remove Adware Using a Trusted Malware Scanner
If pop-ups persist, adware might be installed.
Recommended Action
- Use a reputable malware removal tool
- Avoid cracked or unknown antivirus software
- Scan and remove detected threats
⚠️ Never install antivirus software promoted by pop-ups.
Step 8: Check Installed Programs in Control Panel
Some fake software installs itself silently.
What to Do
- Open Control Panel
- Go to Programs & Features
- Uninstall:
- Unknown programs
- Recently installed suspicious software
- Fake “PC Cleaner” or “Security Tools”
Restart your computer afterward.
Step 9: Update Windows and Your Browser
Outdated systems are easier targets for scam pop-ups.
Keep Updated
- Install latest Windows Updates
- Update your browser to the latest version
- Enable automatic updates for security patches
How to Prevent Virus Warning Pop-Ups in the Future
Prevention is better than cure.
Safety Tips
- Avoid clicking flashy ads and fake download buttons
