If you or a co-worker are not paying attention and accidentally open one of these phishing email attachments, you might infect not only your own workstation, but immediately everyone else’s computer too.
Be very careful when you get an email with an attachment you did not ask for. If there is an attachment, do not click on it but delete the whole email. Remember: “When in doubt, throw it out!”
At work you are about as protected as anyone can be, at home you should be equally as diligent and be backing up important files on removable media. This virus has a ten day incubation period so just because you do not see it today does not mean it is not there.
