Fake antivirus banner advertisement
"⚠️ Your PC may be infected! 4 threats detected. Click here to scan now and remove malware. Microsoft-certified protection — 30-day free trial."
What not to do
- Do not click on banner ads that look like system warnings.
- Do not download antivirus software from an ad or pop-up.
- Do not enter your credit card on a 'free trial' that you accessed from an ad.
Safer next step
- Close the website. If you want antivirus, get it directly from a known company's website — Microsoft Defender is built into Windows and free.
- Real Microsoft, Apple, or antivirus warnings appear in the system tray or notification center, not in your web browser.
- If you're not sure if your computer is safe, ask a trusted family member or a local computer shop you've used before.
