The scammers are using multiple approaches. They may warn you of an imminent (fictitious) virus attack on your computer in order to sell you bogus software to deal with it. If you agree, you will not only have done your money but because you will have permitted them access to your computer, they will upload a program that will be used for further malicious purposes.
However, the online article carries a more pernicious warning—identity theft, the technical term being ‘social engineering’. Don’t give out any personal/financial information as scammers could call you back using it to sound legit (like they represent a business you already have dealings with e.g., a gas or electricity utility).
The column advises to not even confirm your name or address with these unsolicited types of calls.
