Really really stressed out! My wireless printer has suddenly not recognised my computer. I have tried a total of 3 hours to sort it. It will print with USB cable in but not without. I tried to call what I thought was HP helpline. They took over control of my laptop. Got my email address and phone number. I realised that they were not genuine when they started talking about irrelevant files and telling me I had loads of trojans they would have to remove. Now I am sitting here crying wondering if they have harmed my computer and the problem is still unresolved :(
