My Son’s New Job

My son has always been a computer whiz and he recently got a part time job as a computer technician at an electronic store.  He told me that there is a new virus that is causing a lot of harm to many people’s computers.  He has had to perform numerous av exe removals this week alone and he fears that it will only get worse.  He says that this is a really bad virus and it can cause a complete crash.  I worry about things like this because a computer is a really expensive thing to replace.  I hope that we don’t get anything like that.
