Hi Boggin,
As to the first question: I did not because I'm not so much concerned about manual backups, but rather about the daily automatic backups that the tweaking.com program does. For several years it did the job well without any notification but then, several months ago, I started to get these notifications almost every night. Even if I would try it in safe mode with networking, I may coincidentally stumble on a day without a problem so the diagnostic value of doing it is questionable. I'm just wondering why the program can't backup a "busy" file on certain days. Could it be that my Antivirus (Yes Avast) doesn't allow it? When I talking about Avast - I did switch to it from AVG about half a year ago.
As to the second question: Avast. I don't recall that I had these 2 issues when I was using AVG, but I have to admit that this is just a general impression/recollection.
Thanks for your reply
