When an alert is ticked the options given are to reinstall the end-point or ignore the alert.
Whilst you may want to ignore the alert, once the alert issue has been cleared wouldn't it be better to 'acknowledge the alert' which is in keeping with the Sophos enterprise console.
The 'ignore' option gives rise to the impression that the user is not bothered about the alert so chooses to ignore it, when in reality it may have been dealt with and then can be acknowledged.
Also if you 'ignore' an alert by mistake - how do you get it back?
