I expect this will repeat a lot of other's findings, but I thought I would try this anyway. On installing, it froze on the Removing Backup Files screen, and forced a cold boot. When up and running, it seemed smooth enough, but refused to update. This may have been because I didn't have a username and password, but where do you get one from? I filled in the form, but no password came through in the email. Further to this, the lack of a right click scan option makes ESETSS a non-runner for me, unless they are going to update it for the full release, in which case I might try it again.
