I just got rid of my second OS on my computer (it was Win7 beta), and there's a leftover folder that refuse to delete.
I can't delete "Users\Dave\AppData\Roaming\SecuROM\UserData" In that folder there's 2 files with weird names, "ЃϵϳЅЂϿϽϯІχϯπρϴϱЄϱЃϵϳЅ" and "ЃϵϳЅЂϿϽϯІχϯπρЂϻϵЉЃϵϳЅ", no file extensions. It keeps telling me:

(Yes I know it says it opens with Mass Effect 2, I don't know why.), but the files are clearly there. I tried restarting, but it still doesn't help. Any suggestions?
