Hacked e mail

Just to let everyone know, if you are on my e mail system, you may get a dodgy, fake e mail. This is a result of being sent something by a colleague, and opening it innocently. Please don’t open it, if you get the option. My entire address book has been hacked, and I am now banned from Yahoo for a while, until things are sorted. Apologies if you are affected. Nothing I have done, I assure you.
