I have been using Limewire, off and on, for a few years. I had a few thousand downloads, most of which were lost because I failed to backup the system. [Always do backups or at least duplicate your files to an external drive. Drives are so inexpensive now, we can keep a couple of them and connect one to update periodically, like off-site storage.] I am in hopes that someone can point to an infection. This person is to have an IT visit and analyse her system. I believe that she will turn out to be a live-alone, non-networked (working by modem) person who visited the wrong site and caught a bug.
