I am posting this on behalf of a friend. The situation is that his computer will not allow programs to run, and he cannot access the internet. When you try to run programs (including Malwarebytes), and/or try to copy items you get a message that suggests that you do not have the correct rights to do the action you are trying to do. The computer before this problem occurred was running AVG Free Anti-Virus, and he tells me (I can only believe him) that no alerts were given of any infection. AVG will not now run. When you try to run internet explorer, a prompt box appears that asks which program you wish to use to 'open the file'. I can start the machine in safe mode, that works, but the only way I can get the machine to do this is to literally cut power to the machine and then switch it back on. F8 on startup doesn't seem to work. So, my first questions are, how can I start the eight steps to cleaning this machine, can I copy the programs needed using the command prompt if I start in Safe mode with command prompt, or do they need to be installed via windows? Alternatively is there any way I can force windows to allow the file copying? One last point, when you start in safe mode I get two user accounts available. When starting normally I get only one. Control panel is available in both modes, but when you click user accounts you get the same error message saying you do not have sufficient rights.
