Is a tech company calling me or popping up on screen asking for payment to remove a virus from my computer a scam?
Yes. This is a classic tech-support scam — no legitimate company monitors your computer remotely and calls you unsolicited about a virus.

Explanation
Tech-support scams use pop-up warnings, audio alerts, or cold calls to create panic about a supposed virus or security breach. A toll-free number or button is provided to 'contact support'. Once you call or connect, the scammer asks for remote access to 'fix' the problem, then either charges a large fee for unnecessary software, steals financial data visible on your screen, or installs genuine malware. Microsoft, Apple, BT, and all other real tech companies do not monitor individual computers and do not call users about detected viruses. If a pop-up appears, close your browser using Task Manager or Force Quit — do not call any number shown, and do not click anything on the pop-up.
Common red flags
- Pop-up or phone call claiming your computer is infected and needs immediate action
- Instructions to call a phone number shown on screen
- Request to install remote access software such as AnyDesk or TeamViewer
- Payment demanded by gift card, wire transfer, or cryptocurrency
- Caller ID appears to show Microsoft, Apple, or a known tech company
What to do now
- Close your browser using Task Manager (Windows) or Force Quit (Mac)
- Do not call any number shown in a pop-up
- Do not allow remote access to your computer
- Run a scan using your existing security software if you are concerned
- Report the incident to your national fraud service
Frequently asked questions
What if the pop-up has an official-looking Microsoft logo?
Logos are easily copied in a webpage. Microsoft does not display pop-up warnings or call users about viruses — any alert claiming to be from them and asking you to call a number is fraudulent.
