Hello again,
Yesterday I've tried so much to bring my desktop back, but I had failed. But when I started my computer this morning, my Desktop was here again.... I thought all problems have gone, but when I ran a scan with Adaware, that key was there again. So when we use active desktop, it appears. If this is really False positive, then should I ignore the scan results from now on?
(Mauserme, thanks by the way.)
