Whenever i open any program from my c drive then after a couple of minutes my PC
i believe that my pc is infected with viruses because it shut downs automatically. this happens only when i open any application from my c drive. otherwise my PC works fine. I cannot even scan my computer since my antivirus is installed in my c drive.
