Fake Tech Support Pop-Up Scam
High RiskOverview
Victims see a fake virus warning pop-up on their screen, often claiming to be from Microsoft, Apple, or Windows Defender. The warning urges them to call a number or click a link to resolve the issue. This is a scam used to steal money, install actual malware, or gain remote access to your device.
Typical Targets
- •Older adults less familiar with technology
- •Anyone browsing and encountering malicious ads
- •People worried about computer security
- •Those who don't recognise fake warnings
Why This Scam Works
- •Pop-ups often lock the browser, creating panic
- •Loud alarm sounds increase fear
- •Microsoft/Apple branding looks official
- •People don't know what real warnings look like
- •Urgency ("Your data is at risk!")
Real Example
“A retired teacher in Cork saw a pop-up saying "Your computer is infected! Call Microsoft Support immediately". She called the number and gave remote access to her computer. The "technician" charged €399 for "premium virus removal" and installed actual spyware. Her banking details were later used for fraudulent purchases.”
