I didn't know this, I'm a rookie. At the time I had problems with Yahoo Messenger's displayed sent and received text, now also solved. But you can help me by telling a method for verifying the integrity of my Windows Script files. I'm an Windows 7 user and I haven't found Windows Script Package for this OS till now. I have a felling that the rootkit virus ****ed up a lot of those files and also the registry of many others. Thank you very much for your answer.
