Like many others I have read on this board, I have a virus. While Malwarebytes finds it every time, it doesn't remove it. It shows up in c:\\windows\assembly\GAC\desktop.ini and the vendor is trojan. I performed a quick scan. The log, after I remove it is posted below. Here's hoping for good luck......
