Dear Louie，I was hoping you could help me with a small problem I've been having. My computer seems to be infected with a serious virus， but I don't know how to get the virus off my hard drive. I have tried the anti-virus software， but it doesn't seem to help. Could you take a look at my computer and give me some suggestions?
So even though the virus is occurring in parts of China， we are happy to see that the number of new infections is falling every day.
