Just to report that I`ve re-started my machine three times now, since my `system is not fully protected` message yesterday.
All have been normal, I mean successful, in the sense that the error message has not re-appeared and now I`m getting `Your system is secured`. Hopefully, yesterday`s problem will be a one-off, though I have a suspicion (based on pure guesswork) that it may have had something (I know not what) to do with Winpatrol Plus verifying my start-up programs and somehow making a mistake. Any thoughts?
Regarding updates: they`re very swift even on my fairly erratic 2Mbps broadband. One thing I`ve noticed, though, is that according to Comodo they`re coming in groups of three. Is this a new policy or just a coincidence?
Many thanks all for your responses.
