The Internet Crime Complaint Center (IC3) has issued a public service announcement warning about a “new twist to the telephone tech support scam“.
In its message, it advises users to be particularly cautious about fake pop-ups telling them that their computers are infected and urging to call a toll free number for assistance:
“In a new twist to the tech support scam, cyber criminals attempt to defraud using another avenue. The scam is executed while a user is browsing the Internet. In this scenario, a website being viewed provided a link to articles related to popular topics. The user clicked the link and was redirected to a website which produced a window that advised the user’s computer had been hacked.
Another window was displayed that contained a telephone number to obtain assistance. The user reported all attempts to close the windows were ineffective. Upon calling the number for assistance the user was connected with an individual who spoke with a heavy foreign accent claiming to be an Apple representative. During the process the user’s web browser was hijacked. Restarting the computer in an attempt to regain access to the Web produced another message with a different telephone number to obtain assistance.”
It's important to understand that Microsoft, Windows, your ISP or any other software company cannot 'see errors with your computer,' and will never call you to notify. Don't follow instructions on screen or what they tell you over the phone.
If they get remoted into your computer, please power down the machine IMMEDIATELY. Running Anti-virus/malware scans afterwards is a safe step to take to make sure your data is safe.
