"File c:\documents and settings\tong's family\local settings\temp\nerodemo12550\toolbar.exe
infected with Application.MWS"
I just received this message when i was away from my computer. So i want to find out the virus but it is not at that directory and i cant find it anywhere in my computer even i enable to view hidden file. What kind of this virus is and will it cause damage to my computer? I had run the deep scanning and still no result for the virus.
