My computer became infected with the Win32/virut virus last night. Having battled for hours this morning I think I have removed it. There is still an error when starting firefox (jl.chura.pc/rl) but that is not the question for now... During the clean up I performed a disk cleanup, which it seems included deleting all thumbnails system wide. Any folders containg photos don't have thumbails, they don't even have an icon, just the folder. Same for all the photos within, just the filename. Changing the view in each folder to 'large icons' makes the thumbnails reappear - for that folder. I have thousands of folders of photos so doing this for each one is not a viable option. All of the photos used in Windows Themes are also now not working. They, like before, do not show up when selecting images to be used within a theme. Selecting a picture to be used for the background just outputs black. I am currently using 7048, but am downloading 7077 (Assuming its not a fake) at the moment. Will upgrading fix my problem?
