Got a virus yesterday. Downloaded pc-cillian trial version and eliminated it. Since I Couldn't repair xp pro I re- imaged the C partition with a known good basic image. Found that I couldn't drag and drop files, run defrag, install programs etc. Found that sll files are det to read only. Changed permisssions to allow everything. Rebooted and still all files are read only. Can't do much work with computer like this. HELP
