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
Restart the PC, and tap F8 as it's starting up. When the advanced boot menu comes up, choose safe mode with command prompt. When the DOS box comes up with the blinking cursor, type %systemroot%\system32\restore\rstrui.exe and press enter. That will open the system restore.
