TeamViewer and similar services have been used to commit technical support scams via telephone calls. People are called, either at random or from a list, by criminals claiming to represent a computer support service that has identified the victim's computer as being infected by malware, most often using the name of companies such as Microsoft. They then ask the victim to give them access to their computer by installing a remote control service, which can allow the attacker to infect the computer with malware or to delete or copy personal files. A Wired journalist investigating the scams was asked by a scammer to install TeamViewer. It was reported that ransomware programs were utilizing TeamViewer as a tool to obtain remote access to infected machines. In the United Kingdom, the Internet service provider TalkTalk blocked many remote access tools to protect its customers from remote service scams. They remain blocked as of April 2019[update].
