ok so i somehow managed to download antimalware doctor onto my computer. in trying to get rid of this, i then managed to select daemon tools from the list to be the programme for windows to open my files with when it didnt know which programme to use. i have tried to run a system restore, but cannot due to the fact that that is also in daemon tools format, and whenever i click on it, all error box pops up which reads "error in command line".
any help on how to fix this would be greatly appreciated. thanks
