@andrew75 that's on already I've had no issues with anything but it won't let the file stay. what would be really good if it was a trojan but I've used this application for 5 years and I know it's not. the application is installed its the op centre that runs dos commands that it won't allow the only issue is that it's only available as part of the installer, not its own download. can you turn Kaspersky off fully for a number of minutes while ill install and then link the op centre to the safe list?
