I Cannot seem to locate the file within the appdata\roaming, however when I type in hvex.exe into search, it comes up with the file, and I click open file location and it isn't in there. So I attempted to delete the file through the searcher, and it says that it cannot be deleted due to it being used elsewhere. I have closed every application and ended every proccess possible (without affecting windows) and it still doesn't let me delete it. Any suggestions?
Thanks
