I am using Windows Vista operating system and my browser is Mozilla Firefox. I want to know how to prevent TROJ_DLOADR.ANL from entering the system. This infection has been detected by the Avast antivirus, that I have installed in my system. It is able to delete it, but the problem is that I cannot understand how it gets into the system. I get the alerts, generally when I browse the internet. Please help me with suitable solutions to this problem.
