Downloaded AVG, it healed 6 viruses, but it still doesn't work properly and this box Limewire with message : one or more files appear to be invalid. Comes from a corrupted installation and tells me to download and install Limewire. And then there a messages like "limegroup.gnutella.gui.guiloader/ startup failure etc.... Any idea where does that come from as I had uninstalled Limewire? What should I do???
