We’ve had a few calls from clients saying that they have had a call from “Microsoft” in regard to problems with their computers. Fortunately most of them have realised that it is a scam and have hung up without doing anything that the caller asks.
If you ignore the fact that Microsoft will never cold call you to provide remote support, then the calls can be pretty convincing, and some people have been duped into executing the scammers software on their computers.
The main aim of the software? To enable the scammers to encrypt your files and then demand a “ransom” in order to unlock them.
Obviously this is situation you want to avoid, as the only way to recover your data is from a backup, and many home users don’t have recent backups if at all.
