LogMeIn123 is safe to use if the company requesting its use is trusted. While many legitimate companies use the service for remote technical support, scammers also use the tool to extort money and load illicit software onto users' computers.
LogMeIn123 is not a virus or malware. The program, which allows remote access of a computer over the Internet, has a legitimate use for technical support to be able to service customers remotely. The suite includes remote login capabilities as well as a chat feature and whiteboard for working with customers.
However, iTnews and NBR both report scammers cold-calling computer owners, impersonating companies such as Microsoft and requesting that users load LogMeIn123. Once this occurs, scammers usually claim to find a problem on the PC and request money to fix it. There are also instances of scammers loading ransomware onto computers, locking a user's PC and demanding money to unlock it.
