are you root?

says it all. See the error that you posted?

Installing software from any repo requires sudo access. Normal userids don't have this authority.

BTW, you probably have very little use for Clam or clamtk. Linux isn't Windows. I only use clam on my email server and a file server that is shared with Windows people.
