While online an antivirus scan pop up appeared on my computer. Shortly after I was unable to access the internet. I have read many forums of programs to install to help, however with this virus I have been unable to run any executable file. I get a message windown security alert application cannot be executed. The file _.exe is infected. Do you want to activate your antivirus software. In addition I cannot access task manager as the same message applies. I cannot access add/remove programs. I cannot boot up in safe mode. Not one program will run, from as simple as the calculator to itunes, to word documents. I always get the application cannot be executed. File calculator.exe, itunes.exe is infected. I reinstalled firefox which now allows it to run. I am looking for any suggestions as I am not sure what to do with a virus that does not allow any other program to be executed
