I am using Windows Vista operating system and my browser is Mozilla Firefox. When I surf the internet, I keep getting the alerts that Downloader.Generic8.UGU has entered into my system. The Avast antivirus that I have installed in my system helps me to get rid of the infection. But the main problem is that i do not know how does Downloader.Generic8.UGU get into the system. If anyone has any idea about the solution for preventing the infection from entering the system, kindly provide the suitable information.
