Thanks for reply, however, I still have some concerns. When you say mint has not signed off on the programs/updates does that mean I am not receiving them over a secure connection? Would this not mean that someone could intercept the downloads and ad in malware. It's not just the updates, when I go to the software portal to get new applications/packages fire-fox does not confirm a secure connection. In fact firefox warns me even when I put my password in to log on to this forum account that there is no secure connection, which would mean my password is at risk of being seen by someone else, does it not. Secure connections are confirmed on every other site where it is required by firefox. I no I'm being an annoying newbie but I need a bit more of a detailed explanation to allay my concerns please. Thank you for your help so far though. Regards, Steve.
