I have been cleared of any malware issues by Broni, and celebrated the event by making a backup of my C drive, one I can be confident of. There are just a couple of little issues that are bothering me. This is a bit left field, I have Adobe Lightroom, and any time that I connect a thumb drive or the ATI/ATAPI bridge to my external HDD Lightroom opens, and sometimes WMP will open also. Sometimes I get the normal dialog box with a list of options including "Open folder to view contents" which is what I want to do, but I cannot select this in time before Lightroom kicks in. It is irritating and time wasting and if you can suggest a fix that would be helpful. Also whenever I want to remove a thumb drive I click on the icon, choose "eject xyz" and then still get the noise from the computer when I take the drive out, is that normal for Win 7? Finally a lot of people are worried about the Cryptokiller trojan, and ransomeware more generally. How much of a threat is it and what files does it attack? I don't have spare external HDD space to back up everything. One thing I read says it mostly goes for Office or Open org files. Finally in Computer one of my hard drives is displaying a red line instead of a blue one; the drive has 104gb of 1.31tb of storage available, so it is not in imminent danger of being full, so what does the red line mean?
