On my Panda Antivirus program it popped up that it had a virus on wininet.dll. It said restart to completely disinfect. I did so but next thing I knew, my yahoo messenger wouldnt come up or anything else with it such as opening the control panel and documents and it says "This application has failed to start because WININET.dll was not found. Re- Installing the application may fix this program" I need to know how i can reinstall it. Can anyone help? I am using Window Vista
