no longer possible to modify my data

Hello,
I installed your software a while ago. Today I deleted avast premium from my computer to reinstall it on my other hard drive (internal) except that your software did not create a folder for this tidy it is install in the middle of my hard drive and I can not do anything else in my hard disk “you do not have the permissions to edit delete these folders” and the app is not recognized by my pc so that I can not even delete it and therefore more nothing to touch in my data: install, edit, delete etc … because your software to “special” permission and it really starts to get drunk (x75 000) I have the usual patience but I ABSOLUTELY need my personal data at the fastest for personal projects and as if it was not enough I am strapped pop up (my pc) in that my basket is damaged but I can not even delete it because your software it takes for the only god on earth so I would really like to sort this out at more quickly because I have a life next door

thank you for helping me soon please (sorry if I was a little irritating but his urge for me)

Did you first install avast at this path? C:\Program Files\Avast Software or did you install it somewhere else?
