Tech support scams are fraudulent schemes where scammers pose as legitimate tech support representatives to trick individuals into providing personal information or money. They often contact victims through phone calls, emails, or pop-up messages, claiming that there is a problem with their computer or software. These scammers may ask for remote access to the victim's device, allowing them to steal sensitive data or install malicious software. Victims are often pressured to pay for unnecessary services or software, leading to financial loss and compromised security. It's important to verify the identity of any tech support before sharing information or making payments.
