Hi there. I've received an email claiming to be from UPS telling me that they had tried to deliver a package (copy attached with links removed). Attached was a zip file which I was told to open and print out. Without thinking I clicked on the link to the file and was taken to what looked like a Word file. At this point I realised this was a mistake and closed the window. I'm a bit worried that it may have been too late and that my computer has been infected. I ran a full McAfee scan and it said there was nothing found. However I read on another site that this is a common scam and and that it downloads a trojan which McAfee may not find. Has anyone else come across this and if so how can I be sure my computer really is clean? Grateful for any advice.
